The answer is letter C. The signing of Treaty of Fort
Jackson
This treaty was signed after the defeat of the Red Sticks in
the Upper Creek. The treaty allowed the government to cede more than 20 million
acres of land of the Native Americans in the
United States.
The Compromise of 1876 effectively ended the Reconstruction era. Southern Democrats' promises to protect civil and political rights of blacks were not kept, and the end of federal interference in southern affairs led to widespread disenfranchisement of blacks voters.
