I didn't know how long you wanted it but here you go, hope this was a good enough description!
Answer:
At the start of the 20th century, there were estimated to be nearly 300,000 Native Americans in the USA, but during the time the number would fluctuate, and that was still a small percent of the population. The history of tension between native Americans and the federal government of the United States has been long going and severely complicated. Before the present century there was the 18th and 19th century where we had deprived most native Americans of their already extremely limited and self-governed reserves and homes from them and even forced them off their own land, taking their resources and crops etc., but with the rising conflict came negotiations and with negotiations came good ol' American treaties, which were rarely honored by the white authority, by the way. In 1903 Supreme court decided that because the treaties defining the tribe's trades, official affairs, and land boundaries were not ratified and the treaty making plan having ended in 1871, the court finally took one of the last things they had, the control of the native's affairs. Conclusively, we took and took, later we made them resettle with acts and which led to many deaths and unfortunate events for the native. Some treaties were tried and borders were moved to control conditions and behaviors between the two parties but were never kept in the end. We considered them domestic because we made them domestic.
hope this kinda gave you an outline
