A law that forced Indigenous tribes to move west of the Mississippi River is known as which term?

• A. Immigrant
• B. Iron Curtain
• C. Indian Removal Act
• D. Iwo Jima (Battle)

Answer: (C)

A key idea here is understanding the formal policy that allowed the U.S. government to relocate Native American tribes from their ancestral lands in the east to territories west of the Mississippi. That policy is defined by a specific law passed in 1830, known as the Indian Removal Act. It gave the president authority to negotiate removal treaties with tribes and push them westward, opening eastern lands for settlers. This act underpinned the forced relocations, including the tragic marches that became known as the Trail of Tears. The other terms refer to unrelated things: immigrant describes people moving to a new country to live; the Iron Curtain was a Cold War term for the division of Europe; Iwo Jima was a World War II battle. Because the question asks for the term naming the law that forced removal of Indigenous tribes, Indian Removal Act is the precise and correct answer.
