Austrian State Treaty Effective

Date: July 27, 1955 • Location: Rome, Italy

The Austrian State Treaty came into effect, ending the Allied occupation of Austria, although the country was not free of Allied troops until October.

The Austrian State Treaty or Austrian Independence Treaty established Austria as a sovereign state. It was signed on 15 May 1955 in Vienna, at the Schloss Belvedere among the Allied occupying powers and the Austrian government. The neighbouring Federal People's Republic of Yugoslavia acceded to the treaty subsequently. It officially came into force on 27 July 1955.
