Final answer:
The Dominion of New England increased British authority over the colonies by revoking local assemblies, placing the Dominion under direct control of an appointed governor-general, expanding male suffrage, and establishing an Anglican Church in Boston. Sir Edmund Andros served as the first royal governor.
Step-by-step explanation:
The Dominion of New England was established in 1684 by the British Crown, which combined all the New England colonies, including Massachusetts, New Hampshire, Connecticut, Rhode Island, and Plymouth, as well as New York and New Jersey, into a single administrative unit. Through this consolidation, the British increased their authority over the colonies by revoking local assemblies, placing the Dominion under the direct control of a governor-general appointed by the Crown, and expanding male suffrage. The establishment of an Anglican Church in Boston also ended the Puritan monopoly. Sir Edmund Andros was appointed as the first royal governor of the Dominion.
