Step-by-step explanation:
The Native Americans believed that nobody owned the land. Instead, they believed the land belonged to everybody within their tribe. The Europeans, on the other hand, believed that people had a right to own land. They believed people could buy land, which would then belong to the individual.
Native Americans had a spiritual vision of Nature and could not conceive land ownership as something respectable. European forced the Natives to adapt gradually to their notion of private property and land ownership.
