Progressive Alliance in the context of "Social Democratic Party of Austria"

The Progressive Alliance of Socialists and Democrats (S&D) is the political group in the European Parliament of the Party of European Socialists (PES). The Progressive Alliance of Socialists and Democrats was officially founded as a Socialist Group on 29 June 1953, which makes it the second oldest political group in the European Parliament after the European People's Party Group (EPP Group). It adopted its present-day name on 23 June 2009. Centre-left in orientation, the group mostly comprises social democratic parties and is affiliated with the Progressive Alliance and Socialist International.

Until the 1999 European Parliament elections, it was the largest group in the Parliament, but since then it has always been the second-largest group. During the eighth EU Parliament Assembly, the S&D was the only Parliament group with representation from all 27 EU member states. In the current EU Parliament the S&D is currently composed of 136 members from 25 member states.

The Party of European Socialists (PES) is a social democratic European political party.

The PES comprises national-level political parties from all the European economic area states (EEA) plus the United Kingdom. This includes major parties such as the Social Democratic Party of Germany, the French Socialist Party, the British Labour Party, the Italian Democratic Party, the Portuguese Socialist Party, the Romanian Social Democrat Party and the Spanish Socialist Workers' Party. Parties from a number of other European countries and from the Mediterranean region are also admitted to the PES as associate or observer parties. Most member, associate, and observer parties are members of the wider Progressive Alliance or Socialist International.

The Socialist International (SI) is a political international consisting mostly of social democratic political parties and labour organisations. The SI was founded in support of democratic socialism, albeit it has generally moderated over time.

Although formed in 1951 as a successor to the Labour and Socialist International, it has antecedents in the late 19th century. The organisation currently includes 132 member parties and organisations from over 100 countries. Its members have governed in many countries, including most of Europe. In 2013, a schism in the SI led to the establishment of the Progressive Alliance.

The Socialist Party (French: Parti socialiste [paʁti sɔsjalist], PS) is a centre-left to left-wing political party in France. It holds social democratic and pro-European views. The PS was for decades the largest party of the "French Left" and used to be one of the two major political parties under the Fifth Republic, along with the Rally for the Republic in the late 20th century, and with the Union for a Popular Movement in the early 2000s. It is currently led by First Secretary Olivier Faure. The PS is a member of the Party of European Socialists, Progressive Alliance and Socialist International.

The PS was founded in 1969 from a merger of the French Section of the Workers' International (SFIO), the Convention of Republican Institutions led by François Mitterrand, and other groups. In the 1970s, the PS surpassed the Communist Party's share of the left-wing vote. It first won power in 1981, when Mitterrand was elected president. The PS achieved a governing majority in the National Assembly from 1981 to 1986, and again from 1988 to 1993. PS leader Lionel Jospin lost his bid to succeed Mitterrand as president in 1995 to conservative Jacques Chirac, but he served as prime minister in a cohabitation government from 1997 to 2002, when he was again defeated by Chirac in the presidential election.

The name "Labour Party" (or "Labor Party") is used by political parties around the world, particularly in Commonwealth nations. Historically, these parties are associated with democratic socialism, although not exclusively. Over time, most have evolved into social democratic parties. They are traditionally allied with trade unions and the broader labour movement. Many Labour parties are also members of the Socialist International or participants in the Progressive Alliance.

The Swedish Social Democratic Party, formally the Swedish Social Democratic Workers' Party (Swedish: Sveriges socialdemokratiska arbetareparti [ˈsvæ̌rjɛs sʊsɪˈɑ̂ːldɛmʊˌkrɑːtɪska ˈârːbeːtarɛpaˌʈiː] , S or SAP), usually referred to as The Social Democrats (Swedish: Socialdemokraterna [sʊsɪˈɑ̂ːldɛmʊˌkrɑːtɛɳa] ), is a social democratic political party in Sweden. The party is a member of the Progressive Alliance and the Party of European Socialists.

Founded in 1889, the SAP is the country's oldest and currently largest party. From the mid-1930s to the 1980s, the Social Democratic Party won more than 40% of the vote. From 1932 to 1976, the SAP was continuously in government. From 1982 to 2022, the party was in government with the exception of the periods 1991–1994 and 2006–2014. Since 2022, the party has been out of government. It participates in elections as "The Workers' Party – The Social Democrats" (Swedish: Arbetarepartiet – Socialdemokraterna [ˈârːbeːtarɛpaˌʈiːɛt sʊsɪˈɑ̂ːldɛmʊˌkrɑːtɛɳa] ). The first female PM in Swedish history, Magdalena Andersson, is the current leader of the Social Democratic Party.

The Peoples' Democratic Party (Turkish: Halkların Demokratik Partisi, acronymized as HDP; Kurdish: Partiya Demokratîk a Gelan), or Democratic Party of the Peoples, is a Turkish political party mainly representing ethnic minorities in Turkey, especially Kurds. Generally left-wing, the party places a strong emphasis on participatory and radical democracy, feminism, minority rights, youth rights, and egalitarianism. It is an associate member of the Party of European Socialists (PES), a consultative member of the Socialist International, and a party within the Progressive Alliance (PA).

Aspiring to fundamentally challenge the existing Turkish–Kurdish divide and other existing parameters in Turkish politics, the HDP was founded in 2012 as the political wing of the Peoples' Democratic Congress, a union of numerous left-wing movements that had previously fielded candidates as independents to bypass the 10% election threshold. The HDP is in an alliance with the Kurdish Democratic Regions Party (DBP), often described as the HDP's fraternal party. From 2013 to 2015, the politicians of the DBP participated in peace negotiations between the Turkish government and the Kurdistan Workers' Party (PKK).

The Socialist Party (Portuguese: Partido Socialista [pɐɾˈtiðu susiɐˈliʃtɐ], PS) is a social democratic political party in Portugal. It was founded on 19 April 1973 in the German city of Bad Münstereifel by militants who were at the time with the Portuguese Socialist Action (Portuguese: Acção Socialista Portuguesa). The PS is a member of the Socialist International, Progressive Alliance and Party of European Socialists, and has eight members in the European Parliament within the Progressive Alliance of Socialists and Democrats group during the 10th European Parliament.

The party won the 1976 general election and formed the first constitutional government after the 1974 revolution, with Mário Soares as prime minister. However, the government was unstable and fell in 1978. The PS lost the 1979 election, but returned to power in 1983, forming, with the Social Democratic Party, a Central Bloc coalition. It lasted two years and in 1985, the party was defeated and went back to opposition, remaining there for 10 years and losing the two following general elections. Under António Guterres, the party won the 1995 general election and returned to power, lasting until 2002, upon the resignation of Guterres. The party made a comeback and won a historic absolute majority in the 2005 general election under the leadership of José Sócrates. By 2011, the economic crisis led the party to lose the 2011 snap election and the party returned to the opposition. Despite losing the 2015 election, the party formed an agreement with the Left Bloc and the Unitary Democratic Coalition and managed to appoint António Costa as Prime Minister. Costa remained in office for 9 years, until 2024, and during his term won two elections, the last one, in 2022, with an absolute majority. After Costa's resignation, the party narrowly lost the 2024 election, thus, returning to opposition. The party again lost the 2025 election by a larger margin and even fell to third place in Parliament for first time since it's revolution in 1974.
