The struggle for Home Rule, along with labour unrest, had led to the formation in 1913 of two major nationalist paramilitary groups who later launched the Easter Rising: the Irish Citizen Army was established by James Connolly, James Larkin and his Irish Transport and General Workers Union (ITGWU) to protect strikers from the Dublin Metropolitan Police during the 1913 Dublin Lockout. The Irish Volunteers were created in the same year by nationalists in response to the formation of the Ulster Volunteers (UVF), an Ulster loyalist body pledged to oppose Home Rule by force.
