Ow did the institution of slavery in england's atlantic seaboard colonies differ from slavery in the caribbean? what accounted for these differences?

Well one thing is the prevalence. In the Caribbean the vast majority of people were enslaved Africans. In British North America, even in the South, most people were white Europeans. The slaves would outnumber the whites, and in South Carolina there were eventually more slaves than whites. But overall, whites still predominated. This numerical superiority gave the white population in North American more freedom to oppose the British homeland. The whites in the Caribbean colonies had many of the same grievances as North Americans in the 1760s and 1770s, but they were far more dependent on the British military to keep them safe from their slave majorities.
