Austrian State Treaty

The Austrian State Treaty (German: Österreichischer Staatsvertrag [ˈøːstəraɪçɪʃɐ ˈʃtaːtsfɛɐ̯ˌtraːk] ^ⓘ) or Austrian Independence Treaty re-established Austria as a sovereign state. It was signed on 15 May 1955 in Vienna, at the Schloss Belvedere among the Allied occupying powers (France, the United Kingdom, the United States, and the Soviet Union) 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.

Its full title is "Treaty for the re-establishment of an independent and democratic Austria, signed in Vienna on 15 May 1955" (German: Staatsvertrag betreffend die Wiederherstellung eines unabhängigen und demokratischen Österreich, unterzeichnet in Wien am 15. Mai).
