Citroƫn, major French automobile manufacturer that is a subsidiary of the multinational automobile company Stellantis NV.

In 1914 CitroĆ«nās founder, AndrĆ©-Gustave CitroĆ«n, formed his own company to produce munitions during World War I. The company proved so successful that by the end of the war CitroĆ«n was able to buy out the Mors Company, an automobile manufacturer for which AndrĆ©-Gustave CitroĆ«n had previously served as president. In the 1920s the company, which was established as CitroĆ«n SA in 1924, emerged as a major producer of low-priced mass-produced cars. By 1933 it had built 90 percent of the taxicabs operating in Paris.
During the Great Depression, Citroƫn SA fell into financial trouble and was sold to the Michelin company in 1936. During the 1960s Citroƫn was merged with several other automakers. As its financial troubles continued, Peugeot acquired a nearly 40 percent share of Citroƫn in 1974, and the following year it took full ownership. As part of the deal, a new parent company was created, PSA (Peugeot SociƩtƩ Anonyme) Group. In addition to manufacturing cars and trucks, PSA was a major producer of bicycles and motorcycles.

In 1978ā79 PSA acquired the European car- and truck-making units and related finance operations of Chrysler Corporation of the United States, changing the names of these PSA subsidiaries to Talbot. In 1991 the company rebranded itself as PSA Peugeot CitroĆ«n, and in 2016 it took the name PSA Group. The following year the company acquired the German brand Opel and its related British brand Vauxhall from the American carmaker General Motors. The deal was valued at approximately $2 billion. In 2021 PSA Group merged with Fiat Chrysler to form Stellantis.
