STI Unit Overview
This unit examines how the General Allotment Act of 1887 divided Indian lands and paved the way for further development of the United States. Students will learn how the Allotment Act was almost universally applied to all tribes as a large effort to assimilate tribal members, but affected each tribe in different ways. They will compare and contrast the economic success, current political status, and social conditions affecting tribes. Students will discuss whether tribes greatly affected by the Allotment Act fare better than tribes whose land base has been relatively undivided. "Cultural Interactions" is the corresponding CBA.

By the end of instruction, students will:

  • Recognize the Allotment Act of 1887 as landmark legislation that affected and continues to affect tribal sovereignty and tribal development.
  • Examine the political, economic, and social effects of the Allotment Act of 1887.

STI Essential Question

  1. What are the ways in which tribes responded to the threats and outside pressure to extinguish their cultures and independence?
