What was the impact of the Jackson Purchase?

The Jackson Purchase was a historic event before it became a region. The transaction involved prolonged negotiations culminating in a treaty between agents of the United States and those of the Chickasaw Indian Nation. Representing the United States were the aging Isaac Shelby, Revolutionary War hero and twice Kentucky governor, and General Andrew Jackson, hero of the Battle of New Orleans and later president. The Chickasaws were represented by their chiefs, head men and warriors including Levi and George Colbert, Chinubby (the Boy King), and Tishomingo. The two sides signed the treaty in northwestern Mississippi on October 19, 1818, it was ratified by the United States Senate and confirmed by President James Monroe on January 7, 1819.
