Provisional Administration (Polish Administracja Zastępcza) was one of the branches of the Department of Internal Affairs of the Government Delegate’s Office at Home in Poland during World War II. It was created in 1940 as a joint initiative of the Headquarters of the Armia Krajowa and the Delegate's Office. It was a kind of shadow administration prepared for the moment of either liberation of Poland or the start of an all-national armed uprising.
