Carpathian Ruthenia during World War II

Carpathian Ruthenia (also called Carpatho-Rus, Subcarpathian Ruthenia, and Transcarpathia) was a region in the easternmost part of Czechoslovakia which in September 1938 became an autonomous region within that country. On 15 March 1939 it declared its independence as the "Republic of Carpatho-Ukraine"; however, on that same day it was occupied and annexed by Hungary.
