Providence is the capital and most populous city of the U.S. state of Rhode Island. The county seat of Providence County, it is one of the oldest cities in New England, founded in 1636 by Roger Williams, a Reformed Baptist theologian and religious exile from the Massachusetts Bay Colony. He named the area in honor of "God's merciful Providence" which he believed was responsible for revealing such a haven for him and his followers. The city developed as a busy port, as it is situated at the mouth of the Providence River at the head of Narragansett Bay.
