The 36th (Ulster) Division was a division of Lord Kitchener's New Army formed in September 1914. Originally called the Ulster Division, it was made up of members of the Ulster Volunteer Force, who formed thirteen additional battalions for three existing regiments: the Royal Irish Fusiliers, the Royal Irish Rifles and the Royal Inniskilling Fusiliers. The division served on the Western Front as a formation of the British Army during World War I.
