Why did the Middle Colonies have such a diverse population? The Quakers in the New England Colonies encourages those different f
rom them to relocate. The population had a higher proportion of slaves than in the Southern Colonies. Port cities attracted people from many different parts of the new world. Because the people who settled there were peaceful, Native Americans joined their communities.
the Middle Colonies were the most ethnically diverse and also the most religiously diverse colonies because, they were settled by different nationalities, so there is greater emphasis on religious toleration and cultural diversity, and also with settlers coming from all parts of Europe many were indentured servants.
Many of the American Indians who fought in the French and Indian War wre eventually pushed off their land (and of course many were killed as well), since the British won the war.
