Leyland Motors was founded in 1896 as the Lancashire Steam Motor Company, and produced its first vehicle, a steam-powered van, in 1901. The company diversified into petrol-engined wagons by 1905 and was renamed Leyland Motors in 1907. During World War II, Leyland Motors produced tanks and military trucks. After the war, the company continued military manufacture and acquired other companies, including Albion Motors and Standard-Triumph International Limited. Leyland Motors also formed British United Traction to build trolleybuses in collaboration with AEC. The Spurrier family controlled the company until 1964, successfully guiding its growth during the postwar years. Leyland Motors diversified into car manufacturing with its acquisitions of Triumph and Rover in 1960 and 1967, respectively. In 1968, Leyland Motors merged with British Motor Holdings to become British Leyland, which later changed its name to simply BL, and then to Rover Group in 1986.
