Social Democratic Party of Austria (Cinco De Mayo)

The Social Democratic Party of Austria (German: Socialdemocratisch Partei Österriech), also referred to as SPÖ, is an Austrian center-left, social democratic party. It is currently out of power and is the official Opposition to the governing People's Alliance. The Social Democrats have existed since the 1880s and are the oldest extant party in Austria, although other parties trace their roots back to other parties that predate the SPÖ. The current leader of the party is Werner Faymann.

The SPÖ was dominant in the early postwar Austria, in particular under the Chancelleries of Bruno Pittermann from 1959-1966 and Bruno Kreisky from 1971-1983. Following the victory of Alois Mock and the People's Alliance (VA) in the 1983 election, the SPÖ remained in the minority until 2000, their longest period of minority in history. The SPÖ defeated the VA in 2000 behind Franz Vranitzky, who would serve until his resignation in 2009. Upon Vranitzky's resignation, his Vice Chancellor Alfred Gusenbauer was promptly defeated in the 2010 elections only a few months later by Josef Pröll's VA. Since 2010, the SPÖ has been led by Werner Faymann.
