Michigan was the birthplace of the American automobile industry. In the early 20th century, automakers such as Ford, General Motors, and Chrysler established headquarters and factories in Michigan, leading to a boom in the state's economy and population. Detroit became known as the "Motor City" and a symbol of American industrial power.
