Citizens Bank, founded in Rhode Island in 1828 as the High Street Bank, is the 15th-largest bank in the United States. The bank began expanding from its single location in Providence in 1871, opening 29 branches throughout the state of Rhode Island. Citizens Bank’s first branch located outside the state of Rhode Island was opened in 1986 in Massachusetts. Citizens Bank was owned by the Royal Bank of Scotland from 1988 until 2015, when RBS became a minority shareholder in the now publicly-traded company. Citizens began a rapid period of expansion in the 2000’s, purchasing large banks in Pennsylvania, New Jersey, and Delaware and establishing itself as one of the largest banking organizations in the mid-Atlantic. The bank now has branches up and down the east coast of the U.S., extending as far north as New Hampshire and as far south as Delaware. The bank also has branches in the Midwest in Ohio, Illinois, and Michigan.
