Why did the Europeans want land from the Indians?

Because Europe was over crowded, so the Europeans came to the Americas to take land from the Native Americans (Indians).

2nd answer:

The early settlers came to the US to have freedom of religion. England later sent over colonists to grow food, tobacco, and so forth, and send these back to England. This process can be described as, "moneymoneymoney".

As the colonies became successful, cobblers were needed, along with blacksmiths, clothiers, cotton and linen growers, and these all required more land. (More "moneymoneymoney).

The unfortunate Indians happened to be in the way, and could not defend themselves against firearms.
