The Royal Warwickshire Regiment, previously titled the 6th Regiment of Foot, was a line infantry regiment of the British Army in continuous existence for 283 years. The regiment saw service in many conflicts and wars, including the Second Boer War and both the First and Second World Wars. On 1 May 1963, the regiment was re-titled, for the final time, as the Royal Warwickshire Fusiliers and became part of the Fusilier Brigade.
In 1968, by now reduced to a single Regular battalion, the regiment was amalgamated with the other regiments in the Fusilier Brigade – the Royal Northumberland Fusiliers, the Royal Fusiliers (City of London Regiment) and the Lancashire Fusiliers – into a new large infantry regiment, to be known as the Royal Regiment of Fusiliers, becoming the 2nd Battalion of the new regiment.
