Providence Plantations. It was one of nine Colonial colleges granted charters before the American Revolution but was the first college in America to accept students regardless of religious affiliation. Revolutionary to Civil War period: 1770–1860 Rhode Island's tradition of independence and dissent gave it a prominent role in the American Revolution. At approximately 2 a.m. on June 10, 1772, a band of Providence residents attacked the grounded revenue schooner HMS Gaspée, burning it to the waterline for enforcing unpopular trade regulations within Narragansett Bay. Rhode Island was the first of the thirteen colonies to renounce its allegiance to the British Crown on May 4, 1776.
