the borough was annexed by the city of Philadelphia through the Act of Consolidation, 1854. Frankford was historically a manufacturing center, beginning with a gristmill constructed in the 1660s. This same mill became famous during the American Revolutionary War due to the heroics of Lydia Darrah. Before and during the Revolution, two lesser-known grist-mills operated on the creek above the town of Frankford. In 1771, Robert Morris (a miller) purchased a mill at the junction of the Tacony Creek and Frankford Creek. On November 25, 1773, after receiving permission to dam the creek from a Quaker named Nicholas Waln, a feme-sole trader named Mary Peters established a small grist mill.

The terminus of today's SEPTA Market-Frankford Line, now known as the Frankford Transportation Center, became a major transit hub, with connections to bus and trolley routes extending into Northeast Philadelphia. Residents of Frankford live within walking distance of the terminal. SEPTA's elevated train (the "El") runs through the neighborhood above Frankford Avenue.
