How did government policy motivate settlers to remain on their homestead? why would the government enact such a policy?

Answer/ Explanation:

The U.S. government policy toward Native Americans was frequently one of broken promises. Native American lands, but settlers pushing west, including miners and railroad crews, broke these treaties. Examples from the text may include the following: The Fort Laramie Treaty was an agreement that the Native Americans of the Great Plains would stop following the buffalo in exchange for government protection of their land. Almost immediately, miners began to move onto Native American lands. Other treaties forced tribal leaders to give up land: these were resisted by warriors who attacked settlers and supply trains. In the Sand Creek Massacre, a troop led by Colonel John Chivington attacked a band of noncombatant Cheyenne and killed more than 100 people, even after the chief had raised a white flag signaling peace.
