The 2nd Royal Lancashire Militia (The Duke of Lancaster's Own Rifles) was an auxiliary regiment raised in the county of Lancashire in North West England during the French Revolutionary War. It later became part of the King's (Liverpool Regiment). Although primarily intended for home defence, its battalions served in Ireland and saw active service during the Second Boer War. After conversion to the Special Reserve (SR) under the Haldane Reforms one of its battalions was among just a handful of SR units to see combat during World War I, fighting in many actions on the Western Front from early 1915 until the Armistice in 1918. After a shadowy postwar existence the unit was finally disbanded in 1953.
