The First Terran-Florian War, also called the War of Justice and Liberation by the Florians, was a devastating nine-years conflict fought between the Greater Terran Union (as well its vassals) and the Florian Matriarchy-led Stellar Axis. The war lasted from 6th July 2520 and ended on 14th April 2529, beginning during the final stages of Operation Starhammer, the Terran first crusade against the Vol Hive.
The war was ended by the signing of the Treaty of Kaprisi brokered by the Sophox due to the pressure of the observing rival powers of the Milky Way Galaxy at that time, which resulted to the formation of the Commonwealth of Kaprisi as well the Stellar Axis nearly losing its position as one of the major power of the galaxy, having lost four-fifth of its entire standing military along with its resulting economic recession.
Despite the signing of the peace treaty, the sheer devastation and humiliation inflicted toward the Florian become the spark of the decades-spanning Terran-Florian rivalry, with the resulting revanchism resulted into an equally devastating second conflict seven decades later at the height of the War of the Five Fronts.
