Members of the First Dáil - Peter Galligan

Peter Galligan: Fifth Row: Far Right

Peter Paul Galligan (20 June 1888 – 14 December 1966) was an Irish Sinn Féin politician. A member of the Irish Republican Brotherhood and the Irish Volunteers, he was sent to Wexford from Dublin during the Easter Rising to ensure that the volunteers in the area rose to support those in Dublin. He was elected unopposed as a Sinn Féin MP for Cavan West at the 1918 general election.

In January 1919, Sinn Féin MPs who had been elected in the Westminster elections of 1918 refused to recognise the Parliament of the United Kingdom and instead assembled in the Mansion House in Dublin as a revolutionary parliament called Dáil Éireann, though Galligan did not attend as he was in prison. He was re-elected as a Sinn Féin Teachta Dála (TD) for the Cavan constituency at the 1921 elections. He supported the Anglo-Irish Treaty and voted in favour of it. He did not contest the 1922 general election and retired from politics.
