The Terran-Compact War, also known as the Long War among the belligerent nations of the Galactic North, was a series of conflicts which together constitutes one of the longest and bloodiest wars in both the Galactic North’s history as well as the Milky Way as a whole, lasting nearly 232 years, from February 2263 to August 2495. While the war itself began as a conflict between the Algan-Rixian axis and the Terran-Skiron coalition during the Great Skiron War, the conflict eventually spiraled out into a long political, ideological and military conflict between the stratocratic Greater Terran Union (GTU) and the democratic Beneficial Compact

Up until its final years, the War was characterized as a long cold war with periods of open and direct conflict in between (2nd-6th Terran Compact Wars), with the Compact generally on the defensive. However, the unchallenged rise of the GTU’s military and economic prowess soon brought the war into its end during the successful GTU invasion during the Final Terran-Compact War. The Compact is eventually dismantled by the signing of the unequal Treaty of Westminster, turning its member-states into a patchwork of GTU client-states. The GTU in turn become the sole unchallenged power of the Galactic North, turning it into one of the galaxy’s foremost superpowers.

Background

The Greater Terran Union eventually emerges as the humanity’s sole government in the wake of the devastating Tyrum invasion of Earth, spearheading much of its post-war reconstruction. However, the rapid technological progress from the leftovers of past invasion, as well as the need of resources to further development of the Union eventually led to the expansionist policies that define much of the GTU’s history. This led to an aggressive colonization program that saw its territories expanded tenfold in mere decades, and the once-minuscule Space Warfare Branch was reformed into the interstellar Fleet Command to further facilitate the defense and peacekeeping of its ever-expanding territory. It was during this period that the newly-established FLEETCOM began curbing the threat of nationalist, anarchist and revolutionary elements in a series of small scale wars in a war later known as Pirate Wars [1].

First contact with the Algan Republic and the subsequent governments - the Faraxian, Rixians, Skiron and Raltek, were established during the era of expansion as early as 2209. However, the Algan states eventually found itself in conflict with both Terrans and Skirons due to colonization rights as both nations surrounded the Republic, thus reducing the potential avenue for its expansion. Rixians and Faraxian states also developed an increasingly tense relationship with GTU on account of their attempt to claim frontier regions already populated with human colonists.

Tensions flared as the Algan Republic, in an effort to exert pressure against the fractured United Clans of Skiron, eventually formed an alliance with the Rixian Galactic Directorate, with their combined fleets constituting most powerful military force in the galactic "north" at that time. As the Faraxians aligned themselves with Alga-Rixian axis (in part of the democratic revolution funded by the Republic), the Skiron had no choice but to form a defensive pact with the Terran states to maintain the balance of power from tipping to the Algan Republic. These series of alliances were designed to keep each nation in check and, ironically, to prevent a war with one another.

However, the tenuous peace gradually come at the end as information leaked out from the closed borders of the GTU, the triple alliance of Algan, Rixian and Faraxian states eventually learned of the increasing pirate incursions within the Terran border. While the information was outdated, this coincided with recent Algan intelligence reports estimating that the Terran fleet would be unable to match the ships of the alliance. Emboldened, the Tripartite eventually took the initiative by launching the first direct conflict of the Long War.

Early Stages

Great Skiron War

Main article: Great Skiron War

The Rixian Directorate and the Vol Hive, emboldened by the GTU's apparent weakness, declared war against the United Clans on February 16, 2263 and continues their secret build up of its military for their inevitable preemptive war against the GTU-Skiron coalition. Both Algan and Faraxian governments abstained from declaring war.

The war initially went favorably for the Vol-Rixians forces, with many of the Skiron-held system bordering Vol Hive are effectively under their occupation. The Rixians soon took the initiative to capture Thermopylae Station to establish a foothold into Terran space. The Rixian fleet was spotted and tracked by the Union's Skywatch and the Terrans moved to defend it. The Terran Home Fleet led by the Admiral Alexei Dejanus, a veteran of the Pirate Wars, was sent. Alexei’s fleet won an overwhelming victory over the Rixian Star Fleet, forcing them to retreat from the system. Having gained the initiative, the Union pressed on and launched a general offensive. New systems and worlds fell under the Union's banner but the war was beginning to take its toll on the nation's economy.

The GTU quickly establish a defensive line known as the Macmillan-Ramaphosa Corridors along the Rixian-Faraxian-Algan borders, with the war escalating as the Faraxian Union join the war with the Algan Republic following soon after. Nevertheless, the war quickly devolved into a stalemate. With the Vol Hive pulling out of the war and the specter of economic collapse looming over the belligerent nations, all involved sides eventually agreed upon a peace settlement, bringing the war to its end.

However, rather than bringing a peaceful era to the Galactic North, the peace treaty instead led to a beginning of a bitter rivalry between the GTU and the Tripartite. The Algan Republic would reorganize their long-standing alliance into the confederation known as the Beneficial Compact as means to counter the GTU’s rapid expansion and economic rise.

Post-Skiron War actions

While the GTU seized several systems during the war, it's economy was reeling. Ships were scrapped and soldiers were demobilized as the GTU tried to consolidate its gains and re-asses its diplomatic strategy. The Terran-Skiron defensive pact was dissolved as Terrans saw little point in allying itself with a failing state. Instead, the Marshals directed the nation inward, focusing on internal concerns. For the Terran people, the most pressing issue was that of the occupied Faraxian and Rixian worlds and what was to be done to their local populations. The service of Wassari during the war saw a growing support for the GTU's non-human residents, arguing for their right to be citizens.

The newly formed Beneficial Compact, was both weaker and stronger. It's members had lost territory, but had also gained it. The war also strengthened Algan-Rixian-Faraxian ties, with citizens of each state moving freely between their borders and their economies and armies becoming intertwined. But the Compact had little room for expansion, and rightly feared the growing strength of the GTU who had access to vast resources all to itself with little competition. For years to come, they would strive to keep the GTU in check.

The Skiron Defensive War really had no clear winner, but undoubtedly shaped the future of the Galactic North for years to come.

Crisis and Escalation

Golden Age of the Compact

By the end of the Great Skiron War and the subsequent formation of the Compact, the Algan Republic, Faraxian Union and the Rixian Galactic Directorate together underwent an era that could be arguably considered as their first - and only - golden age. As the Compact member-states underwent a rapid economic recovery and its Terran adversary turn increasingly inward, the members of the Compact quickly integrate themselves into the burgeoning quasi-federation with numerous free-trade treaty, joint technological exchanges and military strengthening program under their unity against their common enemy.

With the exception of the Algan Republic, the Compact eventually found itself devoid of option for further colonization, with much of their border are almost surrounded by the Greater Terran Union, the Khelzen, and the now-hostile Vol Hive. This situation prove highly consequential toward their future economic planning, as the lack of colonization effort allows the Compact to devote more resources for industrialization, research, urbanization and further development of its existing, already developed colonies. This in turn led to a rapid modernization, prosperity and increase of quality of life that made the Compact as one of the most advanced economies of the galaxy, being the third largest economies - just behind the Florian Matriarchy and the Ruu Confederated States - although it did not last for long as many other star-nations began to expand their territories and thus its respective economy, especially the GTU.

This golden age are especially advantageous for the Algan Republic; while its fellow allies are forced to rely on foreign trade and export to support their ever growing economy, industry and population, the Algan Republic continues to expand their territory due to the presence of empty region at its border ripe for their colonization effort, which consequently led to the famed Race to the Frontier with the GTU as they rapidly expand their colonization effort across the Outer Rim region. With the territories twice as large as the other Compact members combined and the rich resources that came along with it, the Algan Republic eventually rose as the effective leader of the Compact, and subsequently made it as one of the Great Powers of the era.

However, despite the Algan’s best effort, the majority of the contested Outer Rim region eventually fell under the Terran’s sovereignty and the Republic are effectively lost in their Race to the Frontier. Their rapid development and its prosperity however are enough to at least provide the Compact an equal standing against their much larger adversary, the Greater Terran Union. By the beginning of the Second Terran-Compact War, both the Compact and the GTU are pretty much equal with one another; while the GTU has larger territory and population, greater resources, and stronger military, the Compact in turn boast higher industrialization level, better developed and has more advanced economy than its rival.

Peronisti Incursion

Main article: Terran-Peronisti War

The colonization of the outer rim colonies had brought the GTU into contact with the Peronisti Union. They were located on the far side of the Galactic North, effectively leaving the Union surrounded by potential enemies. Terran High Command, fearing encirclement, began developing contingency plans outlining potential strategies in case of war.

However, following the Skiron Campaigns, the GTU found itself focusing on addressing the economic depression that had gripped the nation as well as the growing unrest in the worlds it had occupied. The period saw the promotion of food growth and energy production, and, at the same time, the quelling of Faraxian revolts on the planet of Rillis. All the while, the Union continued to grow and develop it's frontier colonies.

Terran planners did not really believe the Peronisti Union to be a threat. Even as the Peronisti's political leadership grew continually less Pacifist, they were considered too far away to ever catch the GTU of guard. They were confident that if war was to come, the Home Fleet itself could move from Terra to the Terran-Peronisti frontier before enemy fleets even reach the first Terran controlled system.

On October 10, 2297, the Peronisti Union and the Suth-Vel Confederacy declare war. In a sense, the GTU was proven right in it's assumptions. While many border systems were captured by the enemy, the GTU fleet was able to meet the enemy fleets before they could threaten the core worlds. Despite most of the 1st Expeditionary were out of position, guarding the GTU's border with the Compact, they were able to move to the far side of the of the Terran Union to meet the enemy.

The Peronisti Forces severely outnumbered and outgunned the 1st Expeditionary, forcing them to retreat the Quam system to prepare a defense. In the following Battle of the Binary, the 1st Expeditionary won a decisive victory, halting the Peronisti advance. The Terran battle group, reinforced by the Home Fleet, would then move to reclaim GTU territory. At the decisive Battle of Hlilje, the Peronisti were finally driven from human space.

The war ended on December 18, 2304, just in time for Christmas.

War Plan Case Blue

Main article: Second Terran-Compact War, Three Fortress Campaign

As the conflict against the Peronisti rages on across the Outer Rim and more of the Fleet Command’s assets are directed to the aforementioned region, many of the dissident elements within the GTU became more emboldened against the Terran regime, especially in the volatile Ospranian-Faraxian Occupation Zone in which its systems are heavily populated by Ospranians and Faraxian colonists prior to the Great Skiron War. The first successful revolt within the region occurred on the world of Yeedru, where the pro-Rixian rebels overthrew the local Land Force garrison and rejoined the Directorate soon after its independence. While the Compact neither support nor aware of such news they nonetheless capitalize the event vigorously in a vain attempt to destabilize the GTU, and soon embark to numerous espionage attempt to spark further revolt with no success.

The GTU, already enraged by such action, promptly embarked on a military expansion program in anticipation of a war against their traditional rival. For a long time, both the National Council and the Terran High Command had been designing grand strategy planning known as Case Blue; With many planners anticipated that Compact will try a central thrust via a breakthrough against the Verdun and Thermopylae fortress system (and thus giving it a clear path toward Earth), the Armed Forces capitalizes it by opting for a massive flanking maneuver against the lightly populated Terran-Rixian borders and the Algan’s Outer Rim holdings, leaving behind a sufficient garrison on the Verdun and Thermopylae to wear the Compact main forces out via attrition.

On August 16th, the Terran states, in an attempt to rile the Compact into a war, proceed to present a ten-point ultimatum to the Rixian Galactic Directorate, in which they are given a mere 48 hours to respond as armies and fleets are assembled along the Algan-Rixian borders in the largest military mobilization in GTU’s history that dwarfed even their previous war against the Peronisti. The Terran government already expecting the hostile reaction against the ultimatum amongst the Compact populace. As the Compact are unable to counter the popular demand of war against the GTU, the Compact eventually declare war against their bitter rival, thus giving the GTU a much needed casus belli to enact the War Plan Case Blue, culminating in the Second Terran-Compact War.

Within a year since the war began, the Compact began suffered a string of defeats with the GTU suffered only light casualties in return; the Battle of Tau Cygni and the invasion of Yeedru ends with a decisive victory for the Terran Armed Forces, while the Compact’s ambitious Three Fortress Campaign [2] against the Verdun, Fedeema and Thermopylae system are aborted after a multiple humiliating defeat against the heavily defended Fedeema system that saw much of the Faraxian strength are spent. The war dragged on for more than seven years as the large swath of Algan’s colonies across the Outer Rim, constituting a third of its territories while its militaries are utterly decimated by the end of the war.

As in 12th February 2321, the member-states of the Compact capitulated, culminating to the Armistice of Verdun. While the historians across the galaxy no longer regards this as the end of the Compact, it is certainly the beginning of its long, slow decline; Algan Republic in particular  were stripped of its Great Power status with the loss of its prosperous, resource rich Outer Rim colonies that contribute much of its economic prosperity, as the unity among the Compact's member-states began to show its cracks.

A Broken Compact

Main article: Third Terran-Compact War, Second Siege of Fedeema, First Siege of Nimerium

The aftermath of the disastrous Second Terran-Compact War hit the collective Compact member in both swift and gradual manner. With the Compact’s military failed to capitalize its technological and industrial prowess, much of the notion of strength of the collective security provided by the unity under Compact are irrevocably shattered, and the chaotic and disorganized handling of their war effort on the operational level had in turn began to cast doubt among the Compact’s member-states of their perceived ‘unity’. During the Three Fortress Campaign in particular, it had been the Faraxian’s premature strike against the Fedeema (rather than toward Thermopylae as planned) whose claims are contested by both Faraxians and Rixians, and the Algan’s abruptly redirecting their forces to their Outer Rim colonies are blamed to the main reason for their defeat, much to the detriment of the Rixians who suffered most of the manpower losses.

With their economic and industrial strength remain intact, the Compact is still able to replace the losses suffered during the war with relative ease, with its fleet and army strength were restored to its pre-war level seven years after the Second War. Even then, the catastrophic losses over much of its experienced sailors and troops had damaged much of its institutional knowledge and military tradition, one that they couldn’t recover until the end of the Long War. Furthermore, the loss of the resource-rich Outer Rim regions meant that the Compact is becoming more dependent on export from foreign star-nations to supplement their need of resources which slowly outstrip their local production, especially minerals. This particular deficiencies that exist within their collective military and economies, however subtle they are, will undoubtedly dictate the outcome of the future wars to come.

As the Compact, and the Algan Republic in particular, are desperate in restoring their lost prestige, their focus is turned toward the United Clans of Skiron as the star-nations are gripped into a civil war, the Compact unilaterally declared war against the Skiron, resulting in a short, decisive victory that temporarily restored faith of its respective people. Furthermore, the Algan Republic had been in possession of an abandoned hyper-advanced Tyrum warship found on the Selnoc system during the height of the Second War. Hope began to abound for Algan’s military in the potential technological leap that could turn the tide of the war as the Algan states began to pour their resources to reverse-engineer this newfound relic.

But alas, the quick recovery of the Compact had alarmed the GTU, who intend to completely weaken their bitter rival to further secure its sovereignty, especially after the fall of Skiron who for a long time had earned a special diplomatic and trade relationship with the GTU. Plans are set into motion as the National Council capitalizes on the fall of the Skiron states to justify its propaganda and casus belli for the next war against the Compact. The lightning-speed mobilization of the Fleet and Land Force Command had caught the Compact completely off-guard - even more so for the Algan - culminating into the outbreak of the Third Terran-Compact War in 12th November 2341.

The war had been extremely disastrous for the Compact. With much of the incomplete pre-planned defense line and their reconstructed fleets are swept away in the opening strike, the Compact are reduced to fighting a guerrilla campaign. This is not enough to prevent the conquest of the Algan and Faraxian homeworld in the Lex and Fax system respectively and many of its highly-developed core systems, and even the much needed trump card in the form of the greatly feared Khell’Zen mercenary armadas had suffered defeat during the Second Siege of Fedeema, forcing it to retreat from the war. Even worse is the fact that the much coveted technological leap from their research of the Tyrum vessel are lost with the Fleet Command successfully destroyed the secret research site during their march into Nimerium.

However, the success of the GTU did not last for long. The guerrilla warfare conducted by the Compact had at last prevent the blitzkrieg tactics employed by the Fleet Command from gaining its success, and the much-needed victory during the First Siege of Nimerium at the Selnoc system had at last put the war into a state of stalemate, as well as the much needed morale boost that came with it. The GTU, having gained so much in the war and unable to break the stalemate, wisely agreed to the Compact’s call for a ceasefire, culminating to the signing of the Armistice of Nimerium in 12th of June 2357, ending the war in a favorable term for the GTU and - as many other historian had pointed out - bringing the decisive end of the Compact’s golden age and status as a great power entirely.

Final Conflicts

The Reversed Fortunes

Main articles: Fourth Terran-Compact War, Fifth Terran-Compact War, Warsaw Crisis

The dawn of 25th century are marked by the shifting fortunes of the belligerents of the Long War. After years of successive victories, careful mass terraformation effort and vigorous development program across the entirety of the Terran space, a golden era dawns upon the Greater Terran Union as the nation enjoys a dramatic expansion of its wealth and prosperity. It was at this time period where the Union began to change its outlook as it slowly brought itself out of its self-imposed isolationism, especially with the discovery and (re)activation of the Gateway Network that made contact with the previously unreachable star-nations possible. Trade and immigration restrictions are relaxed significantly, as multiple diplomatic endeavours are made toward the major federations such as the Bright League, Stellar Axis and especially the Star Concord, with the latter even granted trade preferential status as well a large amount of military aid in the form of volunteer armies and military missions upon learning of their centuries-long war against the Tyrum.

The situation of the Compact however are growing bleak. The end of their golden age are marked by the economic depression due to the widespread destruction of their economic heartland, with the Faraxians in particular did not recover up to the end of the Long War. Much of the Algan Republic has been partitioned by the GTU by the signing of the Nimerium Armistice, with its occupied homeworld/capital of Alga in the Lex system along with several other are organized into the confederacy of planetary states known Republican Polenian States, forcing the Republic to shift its capital into the Nimerium and effectively handing over the leadership of the broken confederacy into the still-stable Rixian states.

But while the GTU are wildly successful of its endeavour within its borders and beyond, the situation along its neighbors remain tenuous. Rather than creating a strong buffer zone between the GTU and the Compact, the decentralization of the Republican Polenian States has led into extremely corrupt, fractured and revolt-prone warlord states. Many of its citizens end up were effectively enslaved by the ruling collaborationist, while the incompetent warlord's militia are favored more than the Republican’s professional military which are seen untrustworthy, disloyal and visibly fumed by the corruption of the cabals that carved up the country. On the other side of its border, the strange diplomatic actions and military movement of the Peronisti lead to a revelation of the Great Khan, having recently unified the squabbling Tel’Akkur tribes, and the unnaturally rapid expansion of the Horde brought fear among Terran citizens as it is clear that the Great Khan intend to invade the GTU as well the isolationist Sophox.

It comes into head in the Fourth Terran-Compact War [3], where the Republican armed forces formed the Algan Revolutionary Guard and easily launch a coup d'etat on behalf of Republican’s citizenry, and immediately rejoined the shattered Algan Republic. The GTU initially accept the loss of their troublesome client-states as they are more focused on the immediate threat of the Tel’Akkur Horde, but are forced to act upon learning of the planned surprise invasion of the Compact in their hasty bid to reclaim their lost territories. The fortune does not favor the Compact though, as the resurgent Tel’Akkur empire was cut short by the death of its Great Khan and with it, the abrupt end of its once unstoppable expansionism. This allows the GTU Armed Forces to fully commit its strength to the front and thus putting the war into the end.

The signing of the Treaty of Honshu [4] in 28th July 2399 ends the war with both sides virtually gain nothing, but the strategic victory of the war clearly favors the GTU. Despite the considerable monetary drain necessary in order to retain their once-lost vassal, the Terran states nonetheless able to form the Union of Nimerium, this time with the carefully planned intervention and monitoring of potential corruption and governmental breakdown of its previous Republican incarnation that led to its downfall. On the other hand, the war had effectively break the Compact; the Faraxian suffers perpetual economic depression while the Algan Republic are politically and territorially shattered, while the still-stable Rixian nation now remain to bear the burden of war.

The following decade continues without any remarkable changes. The GTU had effectively recovered economically by then, thus ensuring its growing prosperity remain unhindered as its rival Compact faded into obscurity with its economic collapse and instability began to take its toll. Even with the outbreak of the Fifth Terran-Compact War, the strategic situation remain unchanged. Being the only war formally declared by the Compact themselves, the war was characterized by the clumsy handling of its ‘liberation’ campaign of Nimerium states by the Algan and Faraxians government with no tangible gain, but with one exception - the prosperous Warsaw border system did fall into Compact’s hand due to the rare tactical mistake by the FLEETCOM, leading into a post-war border crisis where its predominantly Polish inhabitants resisted attempts of forced expulsion by the occupying Faraxians. Nevertheless, their failure only rendering their military strength even more impotent as their technological and numerical gap with their Terran opponent grew ever wider.

Byrum Crusade

Main article: Sixth Terran-Compact War, The Byrum Crusade

The GTU had been planning their grand crusade against the Tyrum for a very long time. For this reason, the previously isolationist Terran states even as far as to (successfully) applied to become an Associate Member of the Star Concord, much to the shock of virtually entire galaxy as their association effectively alter the balance of power between the three major federations that dominated the Milky Way with their sheer military prowess. As soon as the GTU gained the association status of the Concord, both Concord and the GTU immediately unveils their long-standing secret military partnership with each other. This act allows the GTU to earn the much needed favor and gratitude of the citizens of the aforementioned federation, thus fostering an unlikely friendship between both power that will stand the test of time. 

However, both the Terran and Concord’s leadership themselves are aware of the geopolitical situation caused by their former’s association with the latter, forcing the GTU to limit their aid toward the Concord with military missions, volunteer forces as well a substantial amount of aid in arms in order to appease the restless Stellar Axis and Bright League while simultaneously bolstering their defenses against the genocidal Tyrum and Prikki-ti-ki. But for the Compact, this news is seen as a disaster for their nation. Already, the Compact immediately cut off any diplomatic relations with their fellow democratic federation in what they saw as ‘the greatest betrayal in the history of galactic democracy’, and the panicked citizenry even as far of demanding for another war against GTU to address this grim situation. 

This string of events led to the political-military crisis where its collective political establishment are divided into two camps; The Doves, comprised of realist-minded military establishments who are against the war, and the Warhawk, the democratically elected officials who relied on the increasingly militant population for political votes. The Doves-dominated military end up marginalized and prosecuted by the Warhawk establishments with many admirals and general were outright dismissed or executed for their ‘dissident actions’, and the Warhawks even as far to establish the so-called Citizen’s Guard, a militia forces independent from - and soon surpass -  the Compact’s standing military to further strengthen their position that soon proves as the worst political undertaking ever committed by the Compact.

The news of the crisis suffered their neighbour were initially welcomed by the GTU as they themselves had been mobilizing practically their entire Armed Forces for their crusade against Tyrum [5], but soon their plan are frustrated by the Compact’s surprise attack along the Terran-Compact border without any warning whatsoever. This culminates into the Sixth Terran-Compact War, concurrent with the ongoing Tyrum’s incursion into Concord’s territories that saw direct military intervention by GTU. Half of their GTU’s mobilized fleet are instead redirected toward the border territories, leading to a score of victories against the short-lived Citizen’s Guard that soon proved itself woefully incompetent as an effective military forces.

But as the war rages on, a shocking news appeared from the other side of the galaxy; the GTU unveils the Sword of Terra, the first of the planet-cracking megaweapon classified as Colossus to the entire galaxy. It was then used to destroy the Tyrum’s homeworld of Byrum, effectively ending the war as the entire Tyrum Queens that serves as the nexus of its hivemind intelligence perished alongside the planet itself, effectively condemning the Tyrum into extinction. As the galaxy reeled on its wholesome destruction, any semblance of morale the Compact need to prosecute the war evaporated instantly. The event itself become a clear indication for its citizenry that the GTU effectively become the strongest military superpower in the galaxy, ending any hope to defeat its bitter enemy any further.

The resulting Armistice of Arcadia was - to put it mildly - disastrous for the Compact. The occupied Warsaw system are quickly returned to the GTU, with some of its vital resource system are reluctantly ceded to their opponent. The Doves-aligned military cabal tries to salvage the situation by dismantling the Citizen’s Guard, improving its original standing military, as well as implementing ad-hoc political and economic reform, but the damage had already been done; the military institution are permanently crippled by the Warhawk’s action, hampering any effort done to repair its shattered collective defenses as the Compact braced itself for another war on the horizon, one that could very well end the federation itself.

Prelude to Final War

After the Crusade, the GTU had been itching to secure its unexpected position of galactic superpower in the wake of Byrum Cataclysm. Meanwhile, the Terran’s show of force during its war against the Tyrum unnerved even its budding ally, the Star Concord, that one of its members the Ruu Confederated Planets even as far to personally led a series of diplomatic conventions during this state of galactic-wide panic. Attempts of  prominent star-nations such as Florian Matriarchy and Xana Commonwealth to muster a galactic intervention in the Terran war against the weakened Compact broke down in part of apathy by the Sophox, political unwillingness of the Concord as well the disagreement between the Axis and League member-states on who should lead the military intervention. This worried the Ministry of Intelligence upon learning the situation as they relayed the information to the National Council, thus strengthening their resolve to end what could be a winnable century-long conflict for the first time in its history.

Plans are set into motion as the Council once again mobilize its forces not long after the Crusade ends, which in turn alarmed the governments of the Compact as they are still struggling to recover from its previous wars. They repeatedly sending diplomatic mission to the GTU for the first time since decades in order to negotiate a peace settlement for the war, only to be rebuffed each time. Attempts to secure aid from foregin nations also bear multiple undesirable results; no nations apart from Florians and Peronisti are willing to offer even a loans to the already debt-ridden federation, while foreign military aid beyond smuggled volunteers are downright impossible with its only border without the hostile GTU right next to it are blocked by the Vol Hive that are equally hostile to everyone. The only sliver of hope they could cling on is the false guarantee from other powers in case of another GTU’s invasion, which at least temporarily put the GTU at bay as it need a sound casus belli for its final invasion.

Fortunately after multiple failed attempt to goad the Compact into the war, the Union’s greatest wish did come true. In 2484, it is discovered that the Algan Workers Revolutionary Forces, one of the largest anti-GTU separatist entities, had been planning for a massive insurrection across the Union of Nimerium and the Terran territories along its border with Compact. While this threat are regarded as a nuisance that could be easily suppressed by local authority, the National Council instead opted for a false-flag operation while pretending as if it doesn't aware of the insurrection. Their long-planned insurrection in 19th of June 2488 went seemingly unhindered as the AWRF proclaimed “the formation of New Algan Republic” with the stated goal to liberate the Polenian race and rejoined the Compact, only to have the aforementioned rebellion being swiftly quashed in the mere 20 hours by the well-prepared Terran military. Despite the Compact’s attempt to denounce the short uprising, the GTU nonetheless ignored the statement, effectively declaring war on the Compact in 29th of July 2488.

Operation Qiyamah

Main article: Final Terran-Compact War, Siege of Farax, Twin Battles of Favellion, Great Raltek Campaign

Upon finishing its declaration of war, the National Council enacted its Operation Qiyamah (Arabic for Judgement Day), and for this purpose had assembled an initial invasion fleet of 120 thousands warships out of its 200 thousands-strong navy. The operation begins with the simultaneous assault across all the major hyperspace lane leading to the Compact’s territories and seizing numerous border system within the few opening months of war. The Algan Republic, now reduced into a one-system nation, are the first to fall - its ruling councilmen of Joinum system quickly made an escape to the Rixian Galactic Directorate as the Nimerium government swiftly took over its administration. 

In the Compact, former general-turned-leader of Compact Ersh na-Seter had expected such plan and quickly mustered a foreign mission to muster any possible foreign intervention against Terran incursion, and had ordered his counterpart Admiral Wash na-Kiler to led the Compact’s remaining manned warships deep into the fortified Rixian territories to preserve its manpower and prepare for a grinding guerrilla campaign, subsequently appointing him as the Compact’s Fleet Chief Commander in the process. Contingency plans were soon drawn up, but it is insufficient and the Compact lack the necessary manned warship due to severe losses it sustained previously - as it stands, the Compact could muster nearly 100 thousand warships on paper, but most of them are merely unmanned crafts of repurposed civilian starships, hastily armed as a mere cannon fodder. Only about 25 thousands of it are true warships, but it is predominantly comprised of semi-outdated corvettes and destroyers, with its largest and most powerful warship are merely a third of the Union-class dreadnought’s size fielded by the GTU.

The GTU, for its part, aware that the Compact will opt for guerrilla warfare and thus opted for a slow march deeper into the confederation, thus ensure a secure line of supply, logistic and communication against any potential attack from its wartime enemy. The Fleet Command did suffer some initial setback during the campaign; chief of it is the unfortunate death of its sole dragonspawn at the hand of the largely unmanned raiding fleet under Admiral Pashna Feljen during a skirmish in Sahara system. In 2489, Ryan’s Raider under Fleet Admiral Joao Filipe Oliviera and its attached Land Force field armies under General Boris Fedorov overrun the Faraxian capital system of Fax and began its siege on its fortified homeworld Farax in May, while a combined fleets of 2nd Expeditionary Fleets and Grey Armada under Fleet Admiral Kim Hae-Young began its probe deep into the Rixian space as well of its nigh-unconquerable vassal-system of the Raltek Confederation. Attempts to slow down her march led into one of the major battles of the war, the Twin Battles of Favellion, occured in January 2489 and March 2490 between the increasingly depleted Compact fleet scrambled together to oppose Hae-Young’s battlegroup, ending with predictable GTU’s victory. However, part of the response fleet was able to escape and avoid complete annihilation because of the well-prepared contingency escape plan on Compact’s behalf.

Alas, despite the Compact’s best effort to stall the invasion, its days are numbered; any hope for foreign aid are beset by the galaxy’s unwillingness to aid the Compact - or in the case of Axis and Bright League, are too preoccupied in their ongoing border conflict with each other. At this point, half of the Compact is under Terran control, which includes the entirety of Faraxian Union, Algan Republic and many of Rixian’s border system. Their only hope lies on the Raltek’s home system of Breek and its myriad of fortress-like homeworld, colonies and stations, in which the Land Force and Fleet Command forced to merge nearly entire of its assembled invasion force to conquer it. The Compact in turn brought its entire surviving fleet and the majority of its combined army to the system for a final stand. This lead to a series of space and planetary battles known as the Great Raltek Campaign, in which the Compact fought for every inch of the system against the much larger Terran invasion force with no avail. While its planets still resisting the continuous Land Force invasion, its fleet are utterly decimated after a grueling one-and-a-half years of space combat, leaving much of the Rixian space completely undefended as the Fleet Command broke through into its space totally unimpeded.

With the complete end of the Great Raltek Campaign and much of its space occupied by the GTU, its despair-driven leadership and weary citizenry surrender unconditionally in 26th of August 2495, ending the war.

Aftermath

By the end of the Long War, the casualties the war brought had reached billions of death on both sides, with the Compact bearing much of the civilian casualties in contrast of the much fortunate GTU who only suffer mostly military casualties. Furthermore, it greatly changed the political and astrographical landscape of the galaxy with the GTU solidified itself as galactic superpower, at the cost of the collapse of the already waning Compact as a sovereign confederacy; the Algan Republic are effectively annexed by the multi-species Union of Nimerium, while the reorganized Faraxian Confederation have its border resource system annexed. Rixian Galactic Directorate are more fortunate with its status only reduced as a highly autonomous client-states of the GTU; any attempt of further control of Rixian states are thankfully averted by virtue of its partially-intact economic prowess.

The end of the war did not bring much desired peace for the GTU; the inevitable ascension of GTU as a superpower were accelerated by its victory in the Long War and thus alerted the pre-existing federations of Star Concord, Bright League and especially the Stellar Axis, making it further isolated and bereft of any potential of friendly states it could rely on. GTU’s budding relation with Florian Matriarchy in particular slowly deteriorates as the leading Axis powers began to saw GTU’s rise as heretical. The waning Vol Hive quickly grew restless, leading to a border dispute with the GTU out of fear. Meanwhile the Sophox Garden of Worlds took a radical shift of its pacifistic isolationism by turning Tel’Akkur’s disparate khanates (which includes the former Peronisti Union) into its tributary upon its recent victory against the aforementioned species simply to strengthen their position against the GTU

Attempts are made to appease the galactic community via Centuries of Peace policies, as the GTU pledges to the Milky Way Galaxy to avoid any further conquest and warfare beyond the war for self-defense. It also embarked on various economic and mega-infrastructural project as a way of peace offering and to strengthen their economic prosperity at the same time, with the Dyson Sphere and Al-Waha Ringworld being the centerpiece of its project. This effort however are partially successful at best; while it manages to mend its relation with the Concord, others remain wary of the GTU as the tension with other major galactic powers remain high, evident by the sudden declaration of war by the Florian Matriarchy against the GTU, merely 25 years after the conclusion of the Terran-Compact Wars.

The effect of mankind's inter-species relation

With the surrender of Compact’s confederacy, its member-states are forced to sign the unequal Treaty of Westminster which officially ending the war and included a number of terms that effectively turned them into the client states of GTU; the treaty required the Compact’s successor states to grant free immigration and military access to its territories for the GTU’s military and citizens (but not the other way around), restricted the amount of carrier and battleship its military could field, as well as several other concessions that effectively grant GTU control over their economic policies and political system. The Treaty however are still seen to be too soft by the more radical political circles of the GTU, as it did not restrict their overall military size (except the capital ships) and had controversially agreed to bear the majority of the debt suffered by Rixian and Faraxian states; such decisions were made by the High Marshal as well part of the National Council in a bid to pacify their newly-acquired vassals.

In contrast of National Council's expectation, the GTU citizenry did not entirely rejected their decision in the signing of the Treaty. Despite still retaining its trademark xenophobic mindset, centuries of friendly contact with the friendly Concord races and their loyal Wessari subjects had slowly changes humanity outlook on the xenos. The best examples could be seen by the ascension of the Galactic Emancipation Organization as the dominant faction of National Assembly, as well the months-long Peace Rally of 2501 in opposition against the forced labor policies imposed on Faraxian, Rixian and Polenian that are instrumental in the gradual abolishment the GTU's xenophobic policies.

By 2515, a series of popular reform known as Aahana's Act are enacted across the GTU in response of increasing humanity's support of xeno's right. For the first time in history, all xenos that hailed from the former Compact or those resided for more than two generation were granted rights of citizen tier status, with the Wessari in particular are granted access of higher tier and right of full military service once reserved for human only. In a way, the end of Terran-Compact War had hastened the shift on humanity's view of xenos, something that are otherwise impossible in the centuries of Greater Terran Union's xenophobic past history

Addendum

- [1] Many historian in the future began to argues that the so-called Pirate Wars are in fact a campaign of suppression against anti government forces at that time rather than a mere piracy suppression campaign, and it is named so as a GTU's way to verbally delegitimatize its opponent - and the fact that said elements indeed conduct some form of piracy to sustain its activities

- [2] Three Fortress Campaign bear a striking similarity with the Battle of Gallipoli during the First World War; the Compact main motivation revolves around opening a straight pathway toward Earth and quickly knock the GTU out of the war (the Entente seek to reopen the Dardanelles to both threaten the Constantinople and secure a route to Black Sea), and both fails due to them severely overestimating their strength and underestimating their enemy simultaneously.

- [3] The exact date when the Fourth Terran-Compact War are still debated to this day; while many historian insist that the war begin with the former Republican's territories rejoined the Algan Republic after the ARG's takeover (23rd February 2381), the Terran government still adamant that the war truly began when the GTU formally declare war three years after the aforementioned coup (7th November 2384)

- [4] The treaty that ends the Fourth War is signed at the colony of Honshu at the star system Yamato, itself are named after the largest island of the Japanese archipelago on Earth. Interestingly, its outcome are more resembles to the Korean War more than 400 years ago.

- [5] Political pressure from the other galactic power meant that any form of military crusade against the Tyrum by the GTU could only be done if the Tyrum themselves attack the Concord's member-states, allowing them to intervene into the war as stipulated by its existing defensive treaty with each other.
