Question: what are the main political parties in ireland
Answer: The two largest political parties , Fianna Fáil and Fine Gael , arose from a split in the original Sinn Féin party in the 1922 -- 1923 Civil War , Fine Gael from the faction ( Cumann na nGaedheal ) that supported the 1921 Anglo - Irish Treaty and Fianna Fáil from the anti-Treaty faction .
