The 1st Somerset Militia was an auxiliary[a] military unit in the county of Somerset in South West England. First organised during the Seven Years' War it served on internal security and home defence duties in all of Britain's major wars. It later became a battalion of the Somerset Light Infantry and supplied thousands of recruits to the fighting battalions during World War I. After 1921 the militia had only a shadowy existence until its final abolition in 1953.
