Early and private life
William Thomas Cosgrave was born at 174 James's Street, Dublin in 1880, to Thomas Cosgrave, grocer, and Bridget (Nixon) Cosgrave. He was educated at the Christian Brothers School at Malahide Road, Marino, before entering his father's publican business. Cosgrave first became politically active when he attended the first Sinn Féin convention in 1905.
He was a Sinn Féin councillor on Dublin Corporation from 1909 until 1922 and joined the Irish Volunteers in 1913, although he never joined the Irish Republican Brotherhood because he didn't believe in secret societies.
He played an active role in the Easter Rising of 1916, serving under Éamonn Ceannt as a Captain at the South Dublin Union. Following the rebellion, Cosgrave was sentenced to death, but that was later commuted to penal servitude for life and he was interned at Frongoch internment camp, Wales.
