How long did the first bank of the United States last?

In February 1791, the First Bank of the United States (1791-1811) received a unique national charter for twenty years. Alexander Hamilton's brainchild, a semi-public national bank, was a crucial component in the building of the early U.S. economy. The Bank prospered for twenty years and performed traditional banking functions in exemplary fashion. With a main office in Philadelphia and eight branches nationwide to serve its customers, the Bank's influence stretched along the entire Atlantic seaboard from Boston to Charleston and Savannah and westward along the Gulf Coast to New Orleans.
