(1589-1676), of Virginia and Maryland, colonizer. In 1631, under a license from Charles I., he established a trading post on Kent Island in Chesapeake Bay. His claim to this involved Virginia and Maryland, as well as himself, in fierce disputes. Lord Baltimore expelled him in 1635, but in 1645 he, in co-operation with Captain Richard Ingle, overthrew the Roman Catholic government. In the following year Calvert was reinstated, but in 1651 Claiborne, as a commissioner of Parliament, reduced Virginia and Maryland to submission.
