Centre-left in the context of "European Free Alliance"

The history of the Italian Republic concerns the events relating to the history of Italy that have occurred since 1946, when Italy became a republic after the 1946 Italian institutional referendum. The Italian republican history is generally divided into two phases, the First and Second Republic.

After the fall of the Fascist regime in Italy and the end of World War II, Italian politics and society were dominated by Christian Democracy (DC), a broad-based Christian political party, from 1946 to 1994. From the late 1940s until 1991, the opposition was led by the Italian Communist Party (PCI). Christian Democracy governed uninterrupted during this period, dominating every cabinet and providing nearly every prime minister. It governed primarily with the support of an array of minor parties from the centre-left to the centre-right, including the Italian Socialist Party (PSI), Italian Democratic Socialist Party (PSDI), Italian Republican Party (PRI), and Italian Liberal Party (PLI), and even far-right parties like the Italian Social Movement (MSI). The Communist Party was excluded entirely from government, with the partial exception of the short-lived Historic Compromise, in which the PCI provided external support to a DC minority government from 1976 to 1979.

Camillo Paolo Filippo Giulio Benso, Count of Cavour, Isolabella and Leri (Italian: [kaˈmillo ˈbɛnso]; 10 August 1810 – 6 June 1861), generally known as the Count of Cavour (/kəˈvʊər/ kə-VOOR; Italian: Conte di Cavour [ˈkonte di kaˈvur]) or simply Cavour, was an Italian politician, statesman, businessman, economist, and noble, and a leading figure in the movement towards Italian unification. He was one of the leaders of the Historical Right and Prime Minister of the Kingdom of Sardinia from 1852, a position he maintained (except for a six-month resignation) until his death, throughout the Second Italian War of Independence and Giuseppe Garibaldi's campaigns to unite Italy. After the declaration of a united Kingdom of Italy, Cavour took office as the first Prime Minister of Italy; he died after only three months in office and did not live to see the Roman Question solved through the complete unification of the country after the Capture of Rome in 1870.

Cavour put forth several economic reforms in his native region of Piedmont, at that time part of the Kingdom of Sardinia, in his earlier years and founded the political newspaper Il Risorgimento. After being elected to the Chamber of Deputies, he quickly rose in rank through the Piedmontese government, coming to dominate the Chamber of Deputies through a union of centre-left and centre-right politicians. After a large rail system expansion program, Cavour became prime minister in 1852. As prime minister, Cavour successfully negotiated Piedmont's way through the Crimean War, the Second Italian War of Independence, and Garibaldi's Expedition of the Thousand, managing to manoeuvre Piedmont diplomatically to become a new great power in Europe, controlling a nearly united Italy that was five times as large as Piedmont had been before he came to power.

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 Sudan People's Liberation Movement (SPLM; Arabic: الحركة الشعبية لتحرير السودان, Al-Ḥarakat ash-Shaʿbiyyat liTaḥrīr as-Sūdān) is a political party in South Sudan. It was initially founded as the political wing of the Sudan People's Liberation Army (SPLA; a key belligerent of the Second Sudanese Civil War) in 1983. On January 9, 2005 the SPLA, the SPLM and the Government of Sudan signed the Comprehensive Peace Agreement, ending the civil war. SPLM then obtained representation in the Government of Sudan, and was the main constituent of the Government of the then semi-autonomous Southern Sudan. When South Sudan became a sovereign state on 9 July 2011, SPLM became the ruling party of the new republic. SPLM branches in Sudan separated themselves from SPLM, forming the Sudan People's Liberation Movement–North. Further factionalism appeared as a result of the 2013–2014 South Sudanese Civil War, with President Salva Kiir leading the SPLM-Juba and former Vice President Riek Machar leading the Sudan People's Liberation Movement-in-Opposition.

Although the party has not adhered to one consistent ideology since the independence of South Sudan and many factions exist, it has been described as "being on the left of centre ideological[ly] speaking," and section IV.2 of the party manifesto states support for a regulated market economy with similar elements to social democracy.

Plaid Cymru (English: /plaɪd ˈkʌmri/ plyde KUM-ree, Welsh: [plaid ˈkəmrɨ]; lit. 'Party of Wales', officially Plaid Cymru – the Party of Wales, and often referred to simply as Plaid) is a centre-left, Welsh nationalist political party in Wales, committed to Welsh independence from the United Kingdom. It campaigns on a platform of social democracy and civic nationalism. The party is a supporter of the European Union and is a member of the European Free Alliance (EFA). The party holds 4 of 32 Welsh seats in the UK House of Commons, 14 of 60 seats in the Senedd, and 200 of 1,234 principal local authority councillors. Plaid was formed in 1925 under the name Plaid Genedlaethol Cymru ('the national party of Wales') and Gwynfor Evans won the first Westminster seat for the party at the 1966 Carmarthen by-election.

In 1999 (in the first devolved Welsh Assembly election), Plaid Cymru gained considerable ground in traditionally Labour heartlands. These breakthroughs were part of the intentional aim to win more seats in the Welsh valleys and North East Wales, which continues to be an ambition today. The party have mostly been in opposition in the Senedd. Although under the leadership of Ieuan Wyn Jones, the party was part of a coalition as a junior partner with Welsh Labour (See: One Wales, Morgan and Jones governments) between 2007 and 2011. Wyn Jones became the deputy First Minister and Minister for the Economy and Transport, other Plaid Cymru Assembly members were also part of the cabinets.

The People's Action Party (PAP) is a major conservative political party in Singapore and is the governing contemporary political party represented in the 15th Parliament, followed by the opposition Workers' Party (WP).

The PAP was established in 1954 as a conventional centre-left party. Following its initial electoral success in 1959, Prime Minister Lee Kuan Yew sought to reposition the party ideologically toward the centre. In pursuit of this objective, he expelled the party's leftist faction in 1961, during the period of Singapore's merger with Malaysia. Over the course of the 1960s and since then, the PAP continued its ideological shift towards the centre-right. After Singapore's separation from Malaysia and subsequent independence in 1965, the majority of opposition parties, excluding the WP, boycotted the 1968 general election. Consequently, the PAP secured all parliamentary seats in that election. In the ensuing decades, the PAP consolidated its political dominance through successive electoral victories. It consistently formed the executive branch of government and exerted substantial influence over key national institutions, including the country's sole trade union, the National Trade Union Congress (NTUC), which is affiliated with the party, as well as the civil service.

Christian Democracy (Italian: Democrazia Cristiana [demokratˈtsiːa kriˈstjaːna], DC) was a Christian democratic political party in Italy. The DC was founded on 15 December 1943 in the Italian Social Republic (Nazi-occupied Italy) as the nominal successor of the Italian People's Party, which had the same symbol, a crusader shield (scudo crociato). As a Catholic-inspired, centrist, catch-all party comprising both centre-right and centre-left political factions, the DC played a dominant role in the politics of Italy for fifty years, and had been part of the government from soon after its inception until its final demise on 16 January 1994 amid the Tangentopoli scandals. Christian Democrats led the Italian government continuously from 1946 until 1981. The party was nicknamed the "White Whale" (Italian: Balena bianca) due to its huge organisation and official colour. During its time in government, the Italian Communist Party was the largest opposition party.

From 1946 until 1994, the DC was the largest party in the Italian Parliament, governing in successive coalitions, including the Pentapartito system. It originally supported liberal-conservative governments, along with the moderate Italian Democratic Socialist Party, the Italian Liberal Party, and the Italian Republican Party, before moving towards the Organic Centre-left involving the Italian Socialist Party. The party was succeeded by a string of smaller parties, including the Italian People's Party, the Christian Democratic Centre, the United Christian Democrats, and the still active Union of the Centre. Former DC members are also spread among other parties, including the centre-right Forza Italia and the centre-left Democratic Party. It was a founding member of the European People's Party in 1976.
