British Colonial America In Colonial America the New England and Chesapeake Region began to develop unmistakable deviation from one another’s societies. This divergence was brought on by copious elements. From the time period of their original settlement in 1607‚ the Chesapeake Region developed differently from the New England Colonies due to their differences in geography‚ motives for settlement‚ and the socioeconomically backgrounds of their original settlers.
