This image is of a broadside that advertised “Indian Land for Sale” in the western states. For more than a century, the United States had been dealing with what white people called the “Indian Problem.” The nation’s population was growing, and its boundaries were pushing westward. President Thomas Jefferson proposed to solve the problem by forcing Native Americans to become farmers. President Andrew Jackson signed into law the Indian Removal Act of 1830, which relocated eastern tribes from their ancestral lands to locations west of the Mississippi River—resulting in the infamous Trail of Tears, when up to 4,000 Native Americans died of starvation, disease, or exposure on the 5,000-mile trek. Between the Civil War and 1911, the West continued to expand rapidly, with Nebraska, Colorado, North Dakota, South Dakota, Montana, Washington, Idaho, Wyoming, Utah, and Oklahoma joining the Union. Much of this growth came at the expense of the Native American tribes who had been forced off their ancestral lands and onto reservations designated by the U.S. government.
