Subcarpathian Rus

Historical region today located mainly in western Ukraine, along the border between Central and Eastern Europe. Also known as Carpathian Ruthenia, this region was part of the Kingdom of Hugray from the 9th Century until the end of WWI. During the interwar period, it constituted the easternmost part of Czechoslovakia. With the partition of Czechoslovakia in 1939, Subcarpathian Rus was again part of Hungary until 1945, when it was ceded to Soviet Ukraine.
