grandymaker [24]

Answer:

New England Colonies - These colonies were founded by puritan separatists. The main reason was to flee religious persecution. Life there was controlled unders strict religious principles, and societal structure was very egalitarian.

Mid-Atlantic Colonies - These colonies were founded by private companies that obtained royal authorization (royal charters). They were characterized by a higher degree of religious diversity, with denominations such as a quakers, catholics, and presbyterians living there.

Southern Colonies - they were the last to be founded. These colonies had a warmer climate that allowed for the development of large cash crop plantations. These plantations led to the importation of thousands of African slaves. However, the backcountry of these colonies was very different, settled mainly by poor white farmers who lived off subsistance agriculture (many of them coming from Scotland and the Ulster).
