The Grossyan-Xeeri Border War (25 avr. 1945 – 24 août 1946)

Description:

Grossya vs Xeeri (Oipientian support)
Grossya claimed the eastern provinces of Xeeri as rightfully and historically theirs.
Oipienta imposed economic sanctions on Grossya and supplied Xeeri with both manpower and resources. Oipienta only supported Xeeri while they did not get directly involved in the war.

The War resulted in a Grossyan victory and the secession of Buvet and Opravek States to Grossya.
