The regiment was originally formed as A Company, Heavy Section, Heavy Machine Gun Corps in May 1916 during the First World War (1914–1918). It took part in the first ever tank offensive in 1916 and saw action on the Western Front again in the Battle of Cambrai in November 1917 and later in the Hundred Days Offensive. Remaining active in the army during the interwar period, in 1939 it was renamed the 1st Royal Tank Regiment.
During the Second World War (1939–1945) the regiment took part in the Siege of Tobruk in the summer of 1941 and the Battle of El Alamein in October 1942, the advance up Italy in late 1943, the Normandy landings in June 1944 and the Western Allied invasion of Germany in 1945. From the Battle of El Alamein the regiment was part of the 22nd Armoured Brigade, itself part of the 7th Armoured Division, for the rest of the war.
After a period based in Germany, 1 RTR helped repelled Communist forces during the Korean War. In 1993, it amalgamated with the 4th Royal Tank Regiment without change of title. It incorporated both the original regiments' traditional recruiting areas of Merseyside and Scotland.
In 1999, two squadrons were split off as part of the Joint Chemical, Biological, Radiation and Nuclear Regiment (CBRN) amalgamating with No. 27 Squadron, RAF Regiment. In December 2011 the Regiment handed over its responsibility for CBRN to the RAF Regiment. On 25 June 2008 at Buckingham Palace, both 1RTR and 2 RTR were presented with their new Standard by The Queen, which included the new Battle Honour of Al Basrah 2003.
On 2 August 2014 the regiment merged with 2RTR to form "The Royal Tank Regiment" (RTR). The new (single battalion) regiment is based at Aliwal Barracks, Tidworth and is one of three armoured regiments equipped with the Challenger II tank.
The history and traditions of 1 RTR will be kept alive in the new regiment by 'Ajax" Squadron.Mildenhall Detachment of the Suffolk Army Cadet Force.
