Socialist International in the context of "Romanian Social Democratic Party (1990-2001)"

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 Socialist Party of Albania (Albanian: Partia Socialiste e Shqipërisë, PSSh), also known as simply the Socialist Party (Albanian: Partia Socialiste, PS), is a social-democratic centre-left political party in Albania. It is the successor to the Party of Labour of Albania, which reconstituted itself under its current name on 13 June 1991 after the fall of communism in an effort to adapt to the new political landscape. It has been the country’s Governing Party since 2013. The Socialist Party is one of the two major parties in Albanian politics along with the Democratic Party. The PS is an associate of the Party of European Socialists and a member of the Socialist International.

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 Progressive Alliance (PA) is a political international of progressive and social democratic political parties and organisations founded on 22 May 2013 in Leipzig, Germany. The alliance was formed as an alternative to the existing Socialist International, of which many of its member parties are former or current members. The Progressive Alliance claims to have 140 participants from around the world.

The Italian Democratic Socialist Party (Italian: Partito Socialista Democratico Italiano, PSDI), also known as Italian Social Democratic Party, was a social-democratic political party in Italy. The longest serving partner in government for Christian Democracy, the PSDI was an important force in Italian politics, before the 1990s decline in votes and members. The party's founder and longstanding leader was Giuseppe Saragat, who served as President of the Italian Republic from 1964 to 1971. Compared to the like-minded Italian Socialist Party, it was more centrist, at least until Bettino Craxi's leadership, in fact, it identified with the centre-left.

After a rightward shift in the 1990s, which led some observers to question the PSDI as a social democratic party, it was expelled from the European Socialist Party. When Enrico Ferri founded with Luigi Preti the current European Liberal Social Democracy (SOLE), which was in favour of an alliance with Silvio Berlusconi's centre-right coalition, the choice was stigmatized by the PES and the Socialist International, and an official statement was issued. In January 1995, the party congress put the current of Ferri and Preti in the minority and elected Gian Franco Schietroma as secretary. After the party was disbanded in 1998, the majority went to the Socialist Party of the centre-left coalition, while the party's right-wing current joined centre-right coalition parties. In 2004, the party was established with the same name, Italian Democratic Socialist Party, which remains a minor party associated with both centre-left and centre-right coalitions.

The Armenian Revolutionary Federation (Armenian: Հայ Յեղափոխական Դաշնակցութիւն, romanized: Hay Heghapokhakan Dashnaktsutyun, abbr. ARF (ՀՅԴ) or ARF-D), also known as Dashnaktsutyun (Armenian: Դաշնակցություն, lit. "Federation"), is an Armenian nationalist and socialist political party founded in 1890 in Tiflis, Russian Empire by Christapor Mikaelian, Stepan Zorian, and Simon Zavarian. As of 2023, the party operates in Armenia, Lebanon, Iran and in countries where the Armenian diaspora is present. The party was also active in Artsakh until the Azerbaijani offensive in September 2023. Although it has long been the most influential political party in the Armenian diaspora, it has a comparatively smaller proportional presence in the Republic of Armenia. As of October 2023, the party was represented in two national parliaments, with ten seats in the National Assembly of Armenia and three seats in the Parliament of Lebanon as part of the March 8 Alliance.

The ARF has traditionally advocated socialist democracy and has been a full member of the Socialist International since 2003; it joined the Second International in 1907. It has the largest membership of the political parties present in the Armenian diaspora, having established affiliates in more than 20 countries. Compared to other diasporan Armenian parties which tend to primarily focus on educational or humanitarian projects, the ARF is the most politically oriented of the organizations and traditionally has been one of the staunchest supporters of Armenian nationalism. The party campaigns for the recognition of the Armenian genocide and the right to reparations. It also advocates the establishment of United Armenia, partially based on the Treaty of Sèvres of 1920.

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 Colombian Liberal Party (Spanish: Partido Liberal Colombiano; PLC) is a centrist to centre-left political party in Colombia. It was founded as a classical liberal party but later developed a more social-democratic tradition, joining the Socialist International in 1999.

The Liberal Party along with the Colombian Conservative Party dominated the Colombian political scene from the end of the 19th century until 2002, in bipartisan political hegemony. The two parties were in direct military conflict between 1948 and 1958, during the civil war period known as La Violencia, after which they established the "National Front", agreeing to rotate power, intercalating for a period of four presidential terms. The election victory of independent candidate Álvaro Uribe in 2002 put an end to dominance of two party politics in Colombia.
