Swiet-Kaisan War

The Swiet-Kaisan War was a conflict between the Swiet tribes of northern Kriehehrdtia and Kaisa. It began in 1319 CE, when Kaisa expanded into Swiet territory in northern Kaisa. The Swiets began attacking Kaisan outposts, and Kaisa responded by enacting a genocide against the Swiet tribes. They killed every person they could find over twelve and under forty, burned settlements, and slaughtered food animals en masse.   Ultimately, nearly a third of the Swiet population was killed, and Kaisan Kriehehrdtia expanded to the north. The Swiet tribes were driven back into the Eechsielochi and have yet to recover.
