To have a land of their own was key for European settlers, since back in their homeland they were unable to do so (they were poor), and land ownership was equivalent to wealth. The more land a person owned, the more powerful and richer he was. Offering such dreamland was the premise for English companies to encourage potential settlers to travel to America.
On the opposite, North American Indians did not believe in land ownership. Everybody was free to own land to live and grow crops in it. They coexisted with nature and constantly moved from land to land, enabling it to recover from their farming activities.
These differences resulted in cruelty towards North American Indians, leading to armed conflicts between them and European settlers.
