Glacier National Park is created on land that the U.S. government pressured members of the Blackfeet nation to sell. Many Blackfeet did not understand the transaction as a sale and thought they were agreeing to a temporary lease. The forced sale followed multiple years of war, illegal settlement, and broken treaty agreements that had promised to provide food and other goods to the Blackfeet community, who had been prevented from practicing their traditional means of subsistence, hunting.

When the park is first created, the advertising campaign uses representations of the the Blackfeet community as a draw to bring visitors from the coasts to the new park. With the creation of the park, courts rule that the Blackfeet can no longer access the land. In 1937, a judge will rule that the Blackfeet can enter the park without paying an entrance fee.
