The Spanish Socialist Workers' Party is a social-democratic political party in Spain. The PSOE has been in government longer than any other political party in modern democratic Spain, namely from 1982 to 1996 under Felipe González; from 2004 to 2011 under José Luis Rodríguez Zapatero; and currently since 2018 under Pedro Sánchez.
The PSOE was founded in 1879, making it the oldest party currently active in Spain. The PSOE played a key role during the Second Spanish Republic, being part of coalition government from 1931 to 1933 and from 1936 to 1939, when the Republic was defeated by Francisco Franco in the Spanish Civil War. The party was then banned under Franco's dictatorship and its members and leaders were persecuted or exiled.
