imposition of Georgia law on the Cherokee was unconstitutional. Horace Greeley alleges that when Jackson heard the ruling, he said, "Well, John Marshall has made his decision, but now let him enforce it." Although the quote may be apocryphal, Jackson made it clear he would not use the federal government to enforce the ruling. Jackson used the power of the federal government to enforce the separation of the Native American tribes and whites. In May 1830, Jackson passed the Indian Removal Act through Congress. It gave the president the right to negotiate treaties to buy tribal lands in the eastern part of the United States in exchange for lands set aside for Native Americans west of the Mississippi, as well as broad discretion on how to use the federal funds allocated to the negotiations. The law was supposed to be a voluntary relocation program, but it was not implemented as one. Jackson's administration often achieved agreement to relocate through bribes, fraud and intimidation, and the leaders who signed the treaties often did not represent the entire tribe. The relocations could be a source of misery too: the Choctaw relocation was rife with corruption, theft, and mismanagement that brought great suffering to that people. In 1830, Jackson personally negotiated with the Chickasaw, who quickly agreed to move. In the same year, Choctaw leaders signed the Treaty of Dancing Rabbit Creek; the majority did not want the treaty but complied with its terms. In 1832, Seminole leaders signed the Treaty of Payne's Landing, which stipulated that the Seminoles would move west and become part of the Muscogee Creek Confederacy if they found the new land suitable. Most Seminoles refused to move, leading to the Second Seminole War in 1835 that lasted six years. Members of the Muscogee Creek Confederacy ceded their land to the state of Alabama in the Treaty of Cusseta of 1832. Their private ownership of the land was to be protected, but the federal government did not enforce this. The government did encourage voluntary removal until the Creek War of 1836, after which almost all Creek were removed to Oklahoma territory. In 1836, Cherokee leaders ceded their land to the government by the Treaty of New Echota. Their removal, known as the Trail of Tears, was enforced by Jackson's successor, Van Buren. Jackson also applied the removal policy in the Northwest. He was not successful in removing the Iroquois
