Describe americas native american policy and how it changed

First question:

The Native American policy in America is the United States government's justified claiming and using of the sole ownership of land owned by the native american tribes called Cherokee. This policy was dominated for the US government's desire for resources and land.

Second question:

30 years later, after the Civil War, although the government policy of the Native Americans were being intended to shift from separation to integration into the American society, the attempts to "Americanize" the Indians caused the death of their own presence and culture in America to occur rapidly. The purpose of the policy, after the aggression, was to have an integration of the Native Americans to become an American society. There were multiple attempts made starting from providing citizenship up to offering lands to the Indians.

the social contract theory

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:
