Leonard Calvert
Leonard Calvert (c. 1606 – 9 June 1647) was an English colonial administrator who served as the first proprietary governor of the Province of Maryland from 1634 until his death.[1][2] The second son of George Calvert, 1st Baron Baltimore, he was appointed to the position by his elder brother, Cecil Calvert, 2nd Baron Baltimore, who held the colonial charter granted by King Charles I in 1632.[1][2] In November 1633, Calvert led approximately 200 settlers aboard the ships Ark and Dove, arriving at what became St. Mary's City in March 1634 after a stop in Virginia, thereby establishing England's fourth permanent North American colony as a haven for Catholics facing persecution in England.[1][3] As governor, he managed military defenses, courts, finances, and relations with Native American tribes, navigating early challenges including trade disputes with Virginia settlers and skirmishes that prompted the construction of fortifications.[1][4] During England's Civil War, Puritan rebels ousted him in 1645, forcing a temporary exile to Virginia where he assembled forces to reclaim control in 1646, restoring proprietary rule until his death from illness the following year.[1][3] His tenure laid the foundation for Maryland's development, including policies promoting religious coexistence between Catholics and Protestants that presaged the colony's later formal toleration act.[2][4]
