Felipe Gonzlez Mrquez (Spanish pronunciation: [felipe onale make]; born 5 March 1942) is a Spanish lawyer, professor, and politician, who was the Secretary-General of the Spanish Socialist Workers' Party (PSOE) from 1974 to 1997, and the 3rd Prime Minister of Spain since the restoration of democracy, from 1982 to 1996. He remains the longest-serving Prime Minister of Spain to be freely elected.

Gonzlez joined the PSOE in 1964, when it was banned under the Francoist regime. He obtained a law degree from the University of Seville in 1965. In 1974, the PSOE elected Gonzlez as its Secretary-General after a split in its 26th Congress. After Franco's death and the beginning of the Spanish transition to democracy, Gonzlez obtained a seat in the Congress of Deputies after he led the PSOE candidacy in the 1977 general election, but lost to Adolfo Surez.

After the PSOE victory in the 1982 general election, Gonzlez formed his first majority government, backed by 202 out of the 350 deputies at the Congress of Deputies, and led the Government of Spain for thirteen and a half years after three additional victories in the 1986, 1989 and 1993 general elections. In 1996, Gonzlez lost the election to Jos Mara Aznar and the People's Party and was elected to the Congress of Deputies for the last time in the 2000 general election, from Seville.

The Spanish Socialist Workers' Party (Spanish: Partido Socialista Obrero Español [paɾˈtiðo soθjaˈlista oˈβɾeɾo espaˈɲol] (listen); abbr. PSOE [peˈsoe] (listen)) 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. Historically a Marxist party, it abandoned Marxism in 1979. Just like most mainstream Spanish political organizations since the mid-1980s, PSOE has been considered by experts to embrace a positive outlook towards European integration.The PSOE has historically had strong ties with the General Union of Workers (UGT), a Spanish trade union. For a couple of decades, UGT membership was a requirement for PSOE membership. Since the 1980s, the UGT has frequently criticized the economic policies of the PSOE, even calling for several general strikes against the PSOE governments on 14 December 1988, 28 May 1992, 27 January 1994 and 29 September 2010, all jointly with the Workers' Commissions, another major trade union. Both the trade unions and the left have often criticized the economic policies of the PSOE for its economic liberal nature, have denounced the policies of deregulation and generalization of the precarious and temporary work, cuts in social benefits such as unemployment and retirement as well as the privatisations of big companies and public services.

The PSOE is a member of the Party of European Socialists, Progressive Alliance and the Socialist International. In the European Parliament, the PSOE's 20 Members of the European Parliament sit in the Socialists and Democrats European parliamentary group.
