To create a government in the Mississippi Territory... The Compact of 1802...
AURORA GENERAL ADVERTISER, Philadelphia, May 13, 1802 Page 2 has: "A Proclamation" signed by the President: Th. Jefferson, which takes over a full column to detail the full text of the treaty between the United States and the Choctaw nation of Indians. Includes are the "X" signatures of 16 chiefs.
This is followed by a "Message" from Jefferson concerning: "...an act for the amicable settlement of the limits with the state of Georgia, and authorizing the establishment of a government in the Mississippi territory...".
This was the "Compact of 1802", an agreement between the United States & the state of Georgia. In it, the U.S. paid Georgia $1.25 million for its central and western lands (the Yazoo lands, now Alabama and Mississippi, respectively), and promised that the U.S. government would extinguish American Indian land titles in Georgia.
