Deuxième arbitrage de Vienne
Hungary began with the First Vienna Award in 1938 (redeeming southern Czechoslovakia with mainly Hungarians) and the Second Vienna Award in 1940 (Northern Transylvania). Through military campaigns it gained the remainder of Carpathian Ruthenia in 1939. In 1941 it added the Yugoslav parts of Bačka, Baranja, Međimurje, and Prekmurje.
