Final answer:
New France and New Netherlands both focused on the fur trade with Native Americans. Treatment towards Native Americans included initial trade cooperation but evolved to conflict in New Netherlands, and the mixing of French settlers with the locals forming the métis community.
Step-by-step explanation:
The colonies of New France and New Netherlands both had a strong focus on the fur trade as their common commercial activity. They established relationships with Native American tribes, with French traders and missionaries often forming alliances and intermingling with local groups, which led to the development of the métis community.
The Dutch initially had friendly trade relations with the natives but as their colony expanded, conflicts arose over trade disagreements and Dutch demands, eventually leading to violence and the enforcement of building defenses, such as Wall Street's origins as a fortification against attacks.
In terms of treatment of American natives, while there were instances of cooperation and relatively peaceful interactions, there were also periods of conflict, particularly as European demands and the effects of trade (such as the spread of diseases and exploitation of native resources) negatively impacted indigenous populations.
The Dutch, facing labor shortages, resorted to the importation of enslaved Africans and sought to involve European immigrants with the promise of economic opportunity and religious toleration.
