The Welsh Tract, also called the Welsh Barony, was a portion of the U.S. state of Pennsylvania settled largely by Welsh-speaking Quakers. It is located to the west of Philadelphia. The original settlers, led by John Roberts, negotiated with William Penn in 1684 to constitute the Tract as a separate county whose local government would use the Welsh language. The Barony was never formally created, but the many Welsh settlers gave their communities Welsh names that survive today. A more successful attempt at setting up a Gwladfa (Welsh-speaking colony) occurred two centuries later, in the Chubut Province of Patagonia, Argentina.
