Ukrainians in Hungary
As a result of the First Vienna Award, the southern part of Transcarpathia became part of Hungary again in 1938. After the breakup of Czechoslovakia in 1939, Hungary occupied and annexed the remainder of Carpathian Ruthenia. After the World War II, it was incorporated into the Soviet Union as a part of the province of the Ukrainian Soviet Socialist Republic by the Treaty of Paris in 1947.
