Can someones explain/tell me what happened when native americans did a treaty, there first contact with europeans, and oral language and settlement?

jacksonian era promoted strength of the presidency and executive branch at the expense of congress. it also sought to broaden the public's participation in government. the jacksonian's demanded to have elected judges, instead of appointed judges, and rewrote many state constitutions to reflect the new values. hope this ! if you did find it would you mind giving me brainliest? : )
