The Dawes Act (1887) allowed the President of the United States to examine Native American tribal land and split it into allotments for specific Native Americans. Those who endured allotments and lived apart from the tribe would be awarded United States citizenship. The Dawes Act would later be amended in 1891, in 1898 by the Curtis Act, and again in 1906 by the Burke Act.
