Thomas West, 12th Baron De La Warr (born July 9, 1577—died June 7, 1618, at sea off the coast of Virginia or New England) was one of the English founders of Virginia, for whom Delaware Bay, the Delaware River, and the state of Delaware were named.
The son of Thomas West, the 11th Baron (c. 1556–1602), the younger West fought in the Netherlands and in Ireland under Robert Devereux, 2nd Earl of Essex. He was imprisoned for complicity in Essex’s revolt against Elizabeth I (1601) but was soon released.
He became a member of the council of the Virginia Company and was appointed (1610) governor and captain general of Virginia for life. Sailing in March 1610 with three ships, 150 settlers, and supplies, he arrived at Jamestown on June 10, in time to intercept the colonists who had embarked for England and were abandoning the enterprise. De La Warr constructed two forts near the mouth of the James River, rebuilt Jamestown, and in general brought order out of chaos.
He returned to London in 1611, where he published, at the request of the company’s council, his Relation (1611, reprinted 1858) of the condition of affairs in Virginia. He remained in England until 1618, when the news of the tyrannical rule of the deputy, Samuel Argall, led him to start again for Virginia. He embarked in May but died en route and was buried at sea.
