The Royal West Middlesex Militia, later the Edmonton Royal Rifle Regiment, was an auxiliary regiment reorganised in Middlesex in the Home counties of England during the 18th Century from earlier precursor units. It later became part of the King's Royal Rifle Corps (KRRC). Primarily intended for home defence, it served in England and Ireland (and briefly in Southern France) during Britain's major wars. It was converted to the Special Reserve under the Haldane Reforms and supplied reinforcements to the KRRC's fighting battalions during World War I. After a shadowy postwar existence the unit was finally disbanded in 1953.
