Final answer:
President Andrew Jackson and the state of Georgia ignored Supreme Court decisions and continued to pressure the Cherokee Nation, leading to the signing of the Treaty of New Echota by the Treaty Party and the subsequent Trail of Tears.
Step-by-step explanation:
The treaty signed by the Creek Nation in 1825 that ceded its remaining land to the state of Georgia was not directly overturned but was followed by a series of legal events and treaties that further impacted the Cherokee Nation. Despite rulings such as Worcester v. Georgia, which stated that non-Native Americans could not enter tribal lands without the tribe's permission, President Andrew Jackson and the Georgia state government ignored the Supreme Court and continued to push for the removal of the Cherokee people. The controversial Treaty of New Echota was signed in December 1835 by a minority faction of the Cherokee Nation, known as the Treaty Party, without the consent of the principal Cherokee leadership, leading to the forced migration known as the Trail of Tears during which approximately 4,000 Cherokee died.
In essence, the treaty signed by the Creek Nation was part of a broader context where the state of Georgia and the federal government under President Jackson were determined to enforce the removal of Native Americans from their ancestral lands, leading to the tragic displacement of not only the Creek Nation but also the Cherokee and other tribes of the Five Civilized Tribes.
