of religious freedom where all were welcome. In 1638 (after conferring with Williams), Anne Hutchinson, William Coddington, John Clarke, Philip Sherman, and other religious dissenters settled on Aquidneck Island (also known as Rhode Island), which was purchased from the local tribes who called it Pocasset. This settlement was called Portsmouth and was governed by the Portsmouth Compact. The island's southern part became the separate settlement of Newport after disagreements among the founders. Samuel Gorton purchased lands at Shawomet in 1642 from the Narragansetts, precipitating a dispute with the Massachusetts Bay Colony. In 1644, Providence, Portsmouth, and Newport united for their common independence as the Colony of Rhode Island and Providence Plantations, governed by an elected council and "president". Gorton received a separate charter for his settlement in 1648 which he named Warwick after his patron. Metacomet was the Wampanoag tribe's war leader, whom the colonists called King Philip. They invaded and burned down several of the towns in the area during King Philip's War (1675–1676), including Providence which was attacked twice. A force of Massachusetts, Connecticut, and Plymouth militia under General Josiah Winslow invaded and destroyed the fortified Narragansett Indian village in the Great Swamp in South Kingstown, Rhode Island on December 19, 1675. In one of the final actions of the war, an Indian associated with Benjamin Church killed King Philip in Bristol, Rhode Island. The colony was amalgamated into the Dominion of New England in 1686, as King James II attempted to enforce royal authority over the autonomous colonies in British North America, but the colony regained its independence under the Royal Charter after the Glorious Revolution of 1688. Slaves were introduced in Rhode Island at this time, although there is no record of any law legalizing slave-holding. The colony later prospered under the slave trade, distilling rum to sell in Africa as part of a profitable triangular trade in slaves and sugar with the Caribbean. Rhode Island's legislative body passed an act in 1652 abolishing the holding of slaves (the first British colony to do so), but this edict was never enforced and Rhode Island continued to be heavily involved in the slave trade during the post-revolution era. In 1774, the slave population of Rhode Island was 6.3% of the total (nearly twice the ratio of other New England colonies). Brown University was founded in 1764 as the College in the British Colony of Rhode Island and
