How did James II and affect political structures in New England?

James II significantly impacted political structures in New England through the consolidation of colonial governance. His establishment of the Dominion of New England in 1686 centralized power by merging several colonies under a single royal governor, Sir Edmund Andros, effectively diminishing local autonomy and self-governance. This move was met with resistance and ultimately contributed to the rise of revolutionary sentiments that led to the Glorious Revolution in 1688, which restored self-governance in the colonies. The Dominion's brief existence highlighted tensions between colonial aspirations for independence and royal authority.
