The division was raised in 1908 as part of the Territorial Force (TF), originally as the East Lancashire Division, and was redesignated as the 42nd Division on 25 May 1915. It was the first TF division to be sent overseas during the First World War. The division fought at Gallipoli, in the Sinai desert and on the Western Front in France and Belgium. Disbanded after the war, it was reformed in the Territorial Army (TA), in the Second World War it served as the 42nd Infantry Division with the British Expeditionary Force (BEF) and fought in Belgium and France before being evacuated at Dunkirk. The division was later reformed in the United Kingdom and, in November 1941, was converted into the 42nd Armoured Division, which was disbanded in October 1943 without serving overseas. A 2nd Line duplicate formation, the 66th Infantry Division, was created when the Territorials were doubled in both world wars.
The King's Regiment (Liverpool) was one of the oldest line infantry regiments of the British Army, having been formed in 1685 and numbered as the 8th (The King's) Regiment of Foot in 1751. Unlike most British Army infantry regiments, which were associated with a county, the King's represented the city of Liverpool, one of only four regiments affiliated to a city in the British Army. After 273 years of continuous existence, the regiment was amalgamated with the Manchester Regiment in 1958 to form the King's Regiment (Liverpool and Manchester), which was later amalgamated with the King's Own Royal Border Regiment and the Queen's Lancashire Regiment to form the present Duke of Lancaster's Regiment (King's, Lancashire and Border).
