List of political parties in the Republic of Ireland

Fianna Fáil is the joint largest party in the Dáil and has the largest number of city and county council seats. It has been in government more than any other party: 1932–1948, 1951–1954, 1957–1973, 1977–1981, 1982, 1987–1994, and 1997–2011. On all occasions up to 1989, it was in a single-party government; on all occasions since then it was the leading party in a coalition government. It is a member of the Alliance of Liberals and Democrats for Europe Party and is led by former minister Micheál Martin. It was founded in 1926 by Éamon de Valera as a radical anti-Treaty party, drawing support from small farmers and urban workers but has since become a party of the establishment. It was first elected to power in 1932 on a constitutional republican platform, promising to remove constitutional links with Britain and reduce poverty by creating employment. It oversaw much of the industrial development of the Republic and has consequently drawn support from all social classes, making it a classic populist party.[4][5][6]

Sinn Féin is the joint largest party in the Dáil and the second-largest party in the Northern Assembly.

Sinn Féin was the party of separatism before Irish independence, and broke through in the Westminster election of 1918, where it won 73 of the 105 Irish seats.

The modern-day Sinn Féin party emerged in 1970 after a split in the party, and was often distinguished as Provisional Sinn Féin. It was closely linked to the Provisional Irish Republican Army. It is led by Mary Lou McDonald.
