Baltimore, Lord, a title of the Calvert family. In 1625 Sir George Calvert was made first Lord Baltimore by James I, and granted land in Newfoundland; but the colony which he founded was a failure. He then petitioned Charles I for a charter to found a new colony, but died (1632) before the charter was issued. His son, Cecil Calvert, second Lord Baltimore, received the charter in June, 1632, and was thus the real founder of Maryland colony. The whole state of Maryland was included in the grant, and Leonard Calvert, a brother of Lord Baltimore, came with an expedition as governor in 1633. Under the Calverts the colony was managed in a wise and tolerant manner.
