In what way (s) does the Dawes act weaken and dismantle the power of Indian nations?

The Dawes Act of 1887 took reservations that were held communally (by the tribe as a whole) and gave them to individuals These individuals were given plots of land by the government in which they were supposed to use in order to become farmers. However, if the Native Americans were shown to be ineffective farmers, the land would be taken back by the federal government. Proving to be an effective farmer posed a challenge, as the land given to the Native Americans in this act was extremely poor for growing crops. Because of this, Native American tribes affected by the Dawes Act lost millions of acres of land of two decades.

Along with this, individuals who were given land as part of the Dawes Act became subject to federal law. This meant that these individuals had to follow the laws of the US instead of their own tribal laws. This is a perfect example of how the Dawes Act weakened/dismantled the power of Indian nations.
