The Homestead Act of 1862, Congress offered land to head of households.
This caused many settlers to migrate west
This caused a lot of issues for the Native Americans who were already there.
The more settlers that came,the more laws the government made which took more and more land from the native Americans which caused conflict because the government was just taking land that the native Americans owned.
The massacre at Wounded Knee signaled the end of the war between settlers and native americans.
The Dawes Act of 1887 was supposed to Americanize the Native Americans. The act broke up the reservations, gave some of the lands to Native Americans. The government was to sell the remainder to white settlers and use the income from that sale for Native Americans to buy farm equipment.
