Who forced the Cherokee to give up their land? I know this is a Connexus question but ANSWER: The U.S. government.

General Winfield Scott

By 1838, only about 2,000 Cherokees had left their Georgia homeland for Indian Territory. President Martin Van Buren sent General Winfield Scott and 7,000 soldiers to expedite the removal process. Scott and his troops forced the Cherokee into stockades at bayonet point while whites looted their homes and belongings.

I believe it was called New Rome, because Constantine moved the capital of the Roman Empire to the city of Byzantine, which he refounded as the city of Constantinople. I hope this helps! :) Have a great day!
