Ethnic Cleansing in the Horsch Confederation

The Western Race War, Confederation Civil War or Ethnic Cleansing in the Horsch Confederation is an ongoing ethnic-purity motivated war in the western regions of the Gretian Empire.
The Horsch Confederation was absorbed into the Gretian Empire in 258 by it's Horsh majority. In 263, tensions began to spark between Hosnia and Horschia, and by 264 had spilled over into race tiors. During The Long Night, Horsh men armed themselves and attacked Hosnian owned businesses in the Confederation capitol of Durastavol. This lead to open war between the states of Hosnia, Moravia, and Horschia. Duvinia attempted to be neutral, but a Duvinian town was attacked by the Moravians.
The Imperial Government quickly grew tired of the fighting and threatened to revoke regional autonomy if the ethnic cleansing wasnt stopped. On the 1st of March, 1309 (265), after the end of winter and the Arcadian Uprising, Gretian soldiers were dispatched to quell the rioting and executions. Airships also partook in bombing the regional capitals to force the states to surrender.
The Gretians agreed to support the Dominion of Mangalore in their war with Nevarro in exchange for extra manpower in the war.
