The 53rd (Welsh) Infantry Division was an infantry division of the British Army that fought in both the First and Second World Wars. Originally raised in 1908 as the Welsh Division, part of the Territorial Force (TF), the division saw service in First World War, being designated 53rd (Welsh) Division in mid-1915, and fought in the Gallipoli Campaign and in the Middle East. Remaining active in the Territorial Army (TA) during the interwar period as a peacetime formation, the division again saw action in Second World War, fighting in North-western Europe from June 1944 until May 1945.
