United States v. Kagama

United States v. Kagama (1886) was a Supreme Court case that addressed the authority of the federal government over Native American tribes. The court ruled that Congress has broad power to legislate for tribal affairs, based on the Constitution's Treaty Clause. The case involved a crime committed on a reservation and questioned whether federal law applied. The decision affirmed that the U.S. had the authority to regulate tribal matters, which reinforced the federal government’s control over Native American sovereignty. This case set a precedent for federal jurisdiction over tribes and their members.
