Liam Cosgrave was first elected to Dáil Éireann in 1943, representing the Fine Gael party. He served as a Teachta Dála (TD) for over 40 years, and held various ministerial positions before becoming Taoiseach (Prime Minister) in 1973. Cosgrave's tenure as Taoiseach was marked by economic challenges and political instability, but he is also remembered for his role in the Northern Ireland peace process.
