<em>Native Americans.</em>
Explanation:
In the early 1800s, white settlers began wanting to expand west, but the land belonged to the Native Americans. The problem was, the Natives did not want to leave whatsoever, and this started to anger the settlers. This was when the Treaty of Echota was brought up, which meant if the Natives traveled to Oklahoma they would keep that land, along with $5 million. Many did not agree to this, which lead to the Trail of Tears, which forced the Natives that did not move west, to walk there in extreme conditions, with little food or water. The Trail of Tears killed most of the Native Americans that took this journey.
Feudalism, also known as the feudal system, was a combination of the legal, economic, military, and cultural customs that flourished in Medieval Europe between the 9th and 15th centuries.
I'm not sure what you meant about the roles but if you mean the social pyramid then I can help with that
C, none of the other answers are true or make sense.
European nations give away land to people willing to settle and work in their colonies, because they have to pay the people to live there, as many of their civilians didn't want to go, for there were no profit in going "Why would we go to an unkonwn place for no profit". The land allowed companies to send settlers there, as people went there to farm or get rich quickly
hope this helps
