The Maryland Toleration Act, also known as the Act Concerning Religion, the first law in North America requiring religious tolerance for Christians. It was passed on April 21, 1649, by the assembly of the Maryland colony, in St. Mary's City in St. Mary's County, Maryland. It created one of the pioneer statutes passed by the legislative body of an organized colonial government to guarantee any degree of religious liberty. Specifically, the bill, now usually referred to as the Toleration Act, granted freedom of conscience to all Christians. (The colony which became Rhode Island passed a series of laws, the first in 1636, which prohibited religious persecution including against non-Trinitarians; Rhode Island was also the first government to separate church and state.) Historians argue that it helped inspire later legal protections for freedom of religion in the United States. The Calvert family, who founded Maryland partly as a refuge for English Catholics, sought enactment of the law to protect Catholic settlers and those of other religions that did not conform to the dominant Anglicanism of Britain and her colonies. The Act allowed freedom of worship for all Trinitarian Christians in Maryland, but sentenced to death anyone who denied the divinity of Jesus. It was revoked in 1654 by William Claiborne, a Virginian who had been appointed as a commissioner by Oliver Cromwell; he was an Anglican, a Puritan sympathizer, and strongly hostile to the Catholic Religion. When the Calverts regained control of Maryland, the Act was reinstated, before being repealed permanently in 1692 following the events of the Glorious Revolution, and the Protestant Revolution in Maryland. As the first law on religious tolerance in the British North America, it influenced related laws in other colonies and portions of it were echoed in the writing of the First Amendment to the United States Constitution, which enshrined religious freedom in American law. Cecil Calvert The Maryland colony was founded by Cecil Calvert in 1634. Like his father George Calvert, who had originated the efforts that led to the colony's charter, Cecil Calvert was Catholic at a time when England was dominated by the Anglican Church. The Calverts intended the colony as a haven for Catholics fleeing England and as a source of income for themselves and their descendants. Many of Maryland's first settlers were Catholic, including at least two Catholic priests, one of whom became the earliest chronicler of the colony's history. But
