At noon on March 22, 1622, the "Great Massacre" occurred. Complete annihilation of all the Jamestown inhabitants by the Powhatan Indian Confederacy was prevented primarily by the warning of an Indian convert, a boy named Chanco. The settlement of Henricopolis (now called Dutch Gap) was completely destroyed: 347 men, women and children--approximately one-third of the total population of the colony--were slain at this time under the strategy of Opechancanough, the leader of the Indians. An ironic happening of the Great Massacre was that one of the victims was George Thorpe, superintendent of the planned college and university of colonial Virginia. He had been a member of Parliament who had sold his estate in England and had come to Virginia to spend his personal fortune and the rest of his life for the conversion and the education of the Indians. By 1619 the General Assembly had set apart 10,000 acres of land for the construction and support of a college for educating Indian youth in "true religion, moral virtue, and civility." The College of Henrico, the first formal educational institution of higher learning in the English colonies, was also destroyed during this Indian Massacre. So strong was the vengeance of the British upon the Indians that no more serious trouble with the Indians occurred until 1644. Some influential people in England who did not approve of a British colony in America tried to encourage the King to abolish the Virginia Company's charter. The Great Massacre gave King James I the opportunity he sought, and, since the company had been unable to pay its dividends, he finally annulled the company's charter on May 24, 1624. Virginia thus became the first royal or crown colony in England's history. The greatest change under the new governmental setup was that now the King, rather than the Virginia Company, appointed the Governor and the councilors, thus making the Governor a royal Governor rather than a company official. King James I died the following year and his son, Charles I, succeeded to the throne. Two years later, the King authorized the General Assembly to meet, primarily in order that he could obtain the excellent monopoly of the Virginia tobacco trade. Much to his surprise, the colonists refused to grant him such monopoly, and, as a result, he did not authorize another meeting for twelve years. From 1629 through 1632, two more provinces were carved from Virginia by royal grants: the Province of Carolina to Sir Robert Heath and the Province of Maryland to Lord Baltimore. The Virginians had not protested much against the grant to Sir Robert Heath, but they did protest strongly against the grant to Lord Baltimore. The leader of this protest was William Claiborne who had previously organized a colony and a trading post on part of the Maryland grant area.
