The United States Motor Company (USMC) was organized by Benjamin Briscoe in 1910 as a selling company, to represent various manufacturers. It had begun life as the International Motor Company in 1908 in an attempt to create a major consolidation within the industry with Maxwell-Briscoe and Buick, which did not succeed. International Motor was renamed USMC in December 1909. By the end of 1910, there were 11 constituent companies, each still headed by the individual who had built each company originally. In 1910, rumors surfaced that United States Motor Company was going to merge with General Motors, but Briscoe scotched the rumors by stating that any attempt to integrate General Motors into USMC would create chaos.

Maxwell was an American automobile manufacturer which ran from 1904 to 1925. The present-day successor to the Maxwell company was Chrysler, now Stellantis North America, which acquired the company in 1925.
