The
Irish Volunteers was a military organisation established in 1913 by
Irish nationalists. It was ostensibly formed in response to the formation of the
Ulster Volunteers in 1912, and its declared primary aim was "to secure and maintain the rights and liberties common to the whole people of Ireland". The Volunteers included members of the
Gaelic League,
Ancient Order of Hibernians and
Sinn Féin, and, secretly, the
IRB. Increasing rapidly to a strength of nearly 200,000 by mid-1914, it split in September of that year over
John Redmond's commitment to the
British War effort, with the smaller group retaining the name of "Irish Volunteers". The Irish Volunteers fought for Irish independence in the
Easter Rising of 1916, alongside the
Irish Citizen Army,
Cumann na mBan, and
Fianna Éireann. From 1919 it took part in the
Irish War of Independence, becoming known as the
Irish Republican Army.
