What is the history of the CoreStates bank?

Written by Editorial Team | Last Updated: August 2026

CoreStates Financial Corp traces its historical lineage back to the founding of the Philadelphia National Bank in 1803, one of the oldest and most prestigious financial institutions in the United States. Over nearly two centuries of operation, the bank expanded its regional footprint through a series of strategic mergers with institutions like Hamilton Bank and First Pennsylvania Corporation, eventually adopting the CoreStates name in the late 20th century. Growing into a dominant regional banking powerhouse in the Mid-Atlantic, CoreStates was acquired by First Union Corporation in 1998 in a massive multi-billion-dollar merger that reshaped the American banking industry.
