The Irish revolutionary leader who orchestrated a government but could not lead it

History · Published 3 October 2026 Swipe more like this →

In short: Richard Mulcahy was a pivotal architect of the Irish Free State, commanding its forces during the Civil War and later uniting disparate parties to end Fianna Fáil's dominance. Yet, his brutal legacy as a wartime commander made him a political pariah, forcing him to step aside from the premiership.

Born in 1886, Richard Mulcahy emerged as a central figure in the Irish struggle for independence. A member of the Irish Republican Brotherhood and the Irish Volunteers, he gained tactical acclaim for his role in the 1916 Easter Rising, specifically the victory at Ashbourne. Alongside Michael Collins, he directed the military campaign against British forces during the War of Independence. Following the 1921 Anglo-Irish Treaty, which he supported, Mulcahy succeeded Collins as commander-in-chief of the National Army during the subsequent Civil War.

Mulcahy’s reputation became inextricably linked to the harsh measures taken by the Provisional Government. He authorized the execution of 77 anti-Treaty prisoners and faced criticism for failing to discipline Free State troops involved in atrocities, particularly in County Kerry. These actions left a lasting scar on his political career. When he successfully engineered a coalition of five parties in 1948 to unseat Éamon de Valera, he was the natural choice for Taoiseach. However, Seán MacBride, leader of the coalition partner Clann na Poblachta, refused to serve under him due to his Civil War record.

To ensure the coalition's survival, Mulcahy famously stepped aside, allowing John A. Costello to become Taoiseach while he remained the nominal leader of Fine Gael. He served as Minister for Education in two inter-party governments before retiring from party leadership in 1959. Despite his long parliamentary career and contributions to the state, the shadow of the 1920s executions remained a defining barrier to his ultimate political ambition. He died in 1971 at the age of 85.
