Kia was founded on June 9, 1944, as Kyungsung Precision Industry, a manufacturer of steel tubing and bicycle parts, eventually producing Korea's first domestic bicycle, the Samchully, in 1951. In 1952, Kyungsung Precision Industry changed its name to Kia Industries, and later built Honda-licensed small motorcycles (starting in 1957) and Mazda-licensed trucks (1962) and cars (1974). The company opened its first integrated automotive assembly plant in 1973, the Sohari Plant. Kia built the small Mazda-based Brisa range of cars until 1981, when production came to an end after the new military dictator Chun Doo-hwan enforced industry consolidation. This forced Kia to give up passenger cars and focus entirely on light trucks. Kia assembled a few hundred more cars in 1982 and 1983, after the ban had taken effect, but no passenger cars were built in 1984 and 1985.
