The Curtis Act of 1898 was an amendment to the Dawes Act. It was about policies concerning the people living in American Indian territories, and it's main objectives were to abolish tribal government, control and register tribe members, amongst other things, in order to integrate the native population into the American society.
The Curtis Act affected the independence and power of American tribes and its members, including the Five Civilized Tribes. Since the Curtis Act's policies and new rules were being forced upon the natives (and affected a huge portion of their lives, including policies concerning land possession and division), many tribe members were against it.
The articles of confederation had no division of powers (branches), the government was too weak to execute laws under the articles, the government couldn't collect taxes, couldn't form a military, etc.
The main concern of the US was with the spread of communism. Hence the wars we fought to try and stop the "domino theory" from coming true.
