Unlike the New England colonies, Virginia sided with Charles I. Its leaders even proclaimed Charles II king after his father’s execution in 1649, although Oliver Cromwell’s government in London soon brought the rebellious colony under control. In Maryland, the combination of the religious and political battles of the Civil War, homegrown conflict between Catholic and Protestant settlers, and anti-proprietary feeling produced a violent civil war within the colony, later recalled as the “plundering time.” Indeed, Maryland in the 1640s verged on total anarchy, with a pro-Parliament force assaulting those loyal to Charles I. The emerging Protestant planter class longed to seize power from the Catholic elite created by Cecelius Calvert. The assembly’s Protestant majority rejected laws proposed by the proprietor and claimed the same power to legislate and levy taxes enjoyed by the House of Commons in England.

To stabilize the colony and attract more settlers, Calvert appointed a Protestant governor and offered refuge to Protestant Dissenters being persecuted in Virginia, where Anglicanism was the established religion and laws restricted the religious and political rights of others. In 1649, Maryland adopted an Act Concerning Religion, which institutionalized the principle of toleration that had prevailed from the colony’s beginning. All Christians were guaranteed the “free exercise” of religion. The Act did not establish religious liberty in a modem sense, since it punished those who denied the divinity of Jesus Christ or the doctrine of the Holy Trinity. Indeed, a Jewish physician was soon arrested under its provisions. Nonetheless, the law was a milestone in the history of religious freedom in colonial America.
Turmoil, however, continued. During the 1650s, the Commonwealth government in London placed Maryland under the control of a Protestant council, which repealed the Toleration Act and forbade Catholics from openly practicing their religion. In 1657, however, Calvert’s authority was restored and with it Maryland’s experiment in religious freedom.
