Oakland, a major West Coast port city, is the largest city in the East Bay region of the San Francisco Bay Area, the third largest city overall in the San Francisco Bay Area, the eighth most populated city in California. It serves as a trade center for the San Francisco Bay Area; its Port of Oakland is the busiest port in the San Francisco Bay, the entirety of Northern California, and the fifth busiest in the United States of America. Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub. Its land served as a rich resource when its hillside oak and redwood timber were logged to build San Francisco.
In 1916, General Motors opened an automobile factory in East Oakland called Oakland Assembly. It produced Chevrolet cars and then GMC trucks until 1963, when it was moved to Fremont in southern Alameda County. Also in 1916, the Fageol Motor Company chose East Oakland for their first factory, manufacturing farming tractors from 1918 to 1923. By 1920, Oakland was the home of numerous manufacturing industries, including metals, canneries, bakeries, internal combustion engines, automobiles, and shipbuilding. By 1929, when Chrysler expanded with a new plant there, Oakland had become known as the "Detroit of the West," referring to the major auto manufacturing center in Michigan.
