Virginia, a band of Puritans in 1642 left for Maryland; they founded Providence (now called Annapolis). In 1650 the Puritans revolted against the proprietary government. They set up a new government prohibiting both Catholicism and Anglicanism. In March 1655, the 2nd Baron Baltimore sent an army under Governor William Stone to put down this revolt. Near Annapolis, his Roman Catholic army was decisively defeated by a Puritan army in the Battle of the Severn. The Puritan Revolt lasted until 1658, when the Calvert family regained control and re-enacted the Toleration Act. In 1689, following the accession of a Protestant monarchy in England, rebels against the Catholic regime in Maryland overthrew the government and took power. Lord Baltimore was stripped of his right to govern the province, though not of his territorial rights. Maryland was designated as a royal province, administered by the crown via appointed governors until 1715. At that time, Benedict Calvert, 4th Baron Baltimore, having converted to Anglicanism, was restored to proprietorship. The Protestant revolutionary government persecuted Maryland Catholics during its reign. Mobs burned down all the original Catholic churches of southern Maryland. The Anglican Church was made the established church of the colony. In 1695 the royal Governor, Francis Nicholson, moved the seat of government to Ann Arundell Town in Anne Arundel County and renamed it Annapolis in honor of the Princess Anne, who later became Queen Anne of Great Britain. Annapolis remains the capital of Maryland. St. Mary's City is now an archaeological site, with a small tourist center. Just as the city plan for St. Mary's City reflected the ideals of the founders, the city plan of Annapolis reflected those in power at the turn of the 18th century. The plan of Annapolis extends from two circles at the center of the city – one including the State House and the other the established Anglican St. Anne's Church (now Episcopal). The plan reflected a stronger relationship between church and state, and a colonial government more closely aligned with Protestant churches. General British policy regarding immigration to all British America would be reflected broadly in the Plantation Act of 1740. Mason–Dixon Line Based on an incorrect map, the original royal charter granted to Maryland the Potomac River and territory northward to the fortieth parallel. This was found to be a problem, as the northern boundary would have put Philadelphia, the major city in Pennsylvania, within Maryland.
