Final answer:
The strongest loyalist support during the American Revolution was in the Carolinas and Georgia, as indicated by the British southern campaign's initial success and significant loyalist enlistment in this region.
Step-by-step explanation:
The strongest amount of loyalist support in the colonies during the American Revolution was in the Carolinas and Georgia. This region saw significant loyalist activity, particularly after the British shifted their military strategy to focus on the South. The British captured Savannah, the capital of Georgia, and found support from thousands of Loyalists, including enslaved individuals who sought freedom by siding with the British forces. Despite the initial success of the British southern campaign, they were eventually defeated at Yorktown with the assistance of French forces and the leadership of American generals like George Washington and Nathanael Greene. In contrast, the middle colonies like Pennsylvania and New York were sharply divided between Patriots and Loyalists, which played into the hands of the British during their military campaigns in these areas. Despite the strong presence of Loyalists in New York City, the region was not the center of loyalist support overall when compared to the southern colonies.
