Firstar Corporation is the former name of what is now U.S. Bancorp, also known as U.S. Bank, a bank corporation in the United States. In 2001, Firstar acquired U.S. Bancorp and assumed its name, moving its headquarters to Minneapolis.
Firstar was founded in 1853 in Milwaukee, Wisconsin, as Farmer's and Millers Bank, becoming First Wisconsin National Bank in 1919 after as a result of internal evolution as well as mergers. The company changed its name to Firstar in 1988.
Firstar expanded through as a series of mergers and buyouts including Banks of Iowa, Federated Bank, First Colonial Bankshares Corporation, and Investors Bank. In 1999, Firstar was purchased by Star Bank (formerly First National Cincinnati of Cincinnati, Ohio) which took the Firstar name, and then bought Mercantile Bancorporation of St. Louis, Missouri five months later.
