The (First) Slovak Republic (), otherwise known as the Slovak State ("Slovenský štát"), was a partially-recognized client state of Nazi Germany which existed between 14 March 1939 and 4 April 1945. The Slovak part of Czechoslovakia declared independence with German support one day before the German occupation of Bohemia and Moravia. The Slovak Republic controlled the majority of the territory of present-day Slovakia but without its current southern parts, which were ceded by Czechoslovakia to Hungary in 1938. It was the first time in history that Slovakia had been a formally independent state.
