Carpatho-Ukraine or Carpathian Ukraine (, ) was an autonomous region within the Second Czechoslovak Republic, created in December 1938 by renaming Subcarpathian Rus' whose full administrative and political autonomy was confirmed by the Constitutional law of 22 November 1938. After the breakup of the Second Czechoslovak Republic, it was proclaimed an independent republic on 15 March 1939, headed by president Avgustyn Voloshyn, who appealed to Hitler for recognition and support. Nazi Germany did not reply, and the short-lived state was returned to the Kingdom of Hungary, crushing all local resistance by 18 March 1939.
