Maryland was settled under a grant to Cecil, Lord Baltimore. The colony was primarily intended as a place of refuge for Roman Catholics, but religious freedom was secured to every Christian denomination except the Unitarians. A fuller degree of self-government also was granted by this first charter than was given in any other colony. An insurrection on the part of the Puritans, who had settled in the colony, temporarily deprived Lord Baltimore of his power, which was, however, restored to him by Cromwell. Civil war between Catholics and Puritans disturbed the peace of the colony until 1701, when Maryland was made a royal province. In 1716 the proprietary rights of the descendents of Lord Baltimore were restored to them and Maryland remained a proprietary colony during the remainder of the colonial period. Maryland was among the most conservative of the colonies on the question of independence.
