Why was congress dissatisfied with the dawes commission in 1898?

Congress was dissatisfied with the Dawes Commission in 1898 primarily because it perceived the commission's efforts to assimilate Native Americans into American society as ineffective and fraught with issues. The commission's land allotment policies often resulted in the loss of tribal lands and culture, leading to significant opposition from both Native American groups and some lawmakers. Additionally, there were concerns about corruption and mismanagement within the commission, which further fueled dissatisfaction among congressional members. Overall, the perceived failure to achieve its objectives led Congress to question the commission's effectiveness and legitimacy.
