FCA US LLC, also known as Fiat Chrysler or simply Chrysler, is the American subsidiary of Fiat Chrysler Automobiles N.V., an Italian controlled automobile manufacturer registered in the Netherlands with headquarters in London, U.K., for tax purposes. FCA US is one of the "Big Three" American automobile manufacturers. FCA US has its headquarters in Auburn Hills, Michigan and sells vehicles worldwide under its flagship Chrysler brand, as well as the Dodge, Jeep, and Ram Trucks. Other major divisions include Mopar, its automotive parts and accessories division, and SRT, its performance automobile division. The Chrysler Corporation was founded by Walter Chrysler in 1925, out of what remained of the Maxwell Motor Company. Chrysler greatly expanded in 1928, when Mr. Chrysler, who at one time worked for Buick, acquired the Fargo truck company and the Dodge Brothers Company and began selling vehicles under those brands; that same year it also established the Plymouth and DeSoto automobile brands. The brand diversification efforts were inspired by Mr. Chrysler's time working for General Motors, with an emphasis on brand hierarchy.
