How did the Indian Reorganization Act improve the life of Native Americans

it provided the return of surplus lands to the tribes rather than to homesteaders. It encouraged written constitutions and charters giving Indians the power to manage their internal occurrences

In contrast to the horrific Indian Removal Act, the Indian Reorganization Act and the Indian Self-Determination and Education Assistance Act aimed to correct many of the mistakes made during the nineteenth century. The Indian Reorganization Act passed in 1934 and gave Native Americans the right to open businesses and created a system through which Native Americans could have access to vocational training and credit. The Indian Self-Determination and Education Assistance Act was even bigger, as it granted tribes the right to govern their own territory (limited tribal sovereignty) while still giving them access to federal money.
