First Tevarin War

The First Tevarin War was an intersystem conflict between the [Tevarin](https://robertsspaceindustries.com/galactapedia/article/V8gJv3nB3X-tevarin) and the [United Planets of Earth (UPE)](https://robertsspaceindustries.com/galactapedia/article/0QxBjKP2PN-united-planets-of-earth). The Tevarin declared war with [Humans](https://robertsspaceindustries.com/galactapedia/article/0Nwpnr6wa2-humans) in 2541, shortly after first contact. The motivations behind the war were complex; it was both a bid for the Tevarin to claim UPE-controlled territory to assuage their overpopulation problem and a consequence of the high cultural value the Tevarin as a people placed on combat. The war was responsible for countless advances in spacecraft technology.
