The Irish Citizen Army, or ICA, was a paramilitary group first formed in Dublin to defend the picket lines and street demonstrations of the Irish Transport and General Workers' Union (ITGWU) against the police during the Great Dublin Lockout of 1913. Subsequently, under the leadership of James Connolly, the ICA participated in the Irish Republican insurrection of Easter 1916.
