Final answer:
The strongest Loyalist support during the American Revolutionary War was in Georgia and South Carolina, where the British exploited societal divisions and promises of freedom to gain support, notably in South Carolina's coastal areas.
Step-by-step explanation:
The strongest amount of Loyalist support in the colonies during the American Revolutionary War was in Georgia and South Carolina. The British were able to capitalize on divisions existing in Southern society, particularly using the promise of freedom to gain support from enslaved individuals who then joined the Loyalist cause in considerable numbers. South Carolinas coastal regions notably had a prevalent Loyalist population. The Revolution ignited a brutal civil war in the backcountry of South Carolina and introduced great violence between the Loyalist and Patriot forces. Georgia and South Carolina became central battlegrounds as the British sought to leverage Loyalist support to regain control of the colonies.
