Acquisition of Louisiana was a long-term goal of President Thomas Jefferson, who was especially eager to gain control of the crucial Mississippi River port of New Orleans. ...

They believed that it would create economic opportunities by offering improved trade, unrealized amounts of natural resources, and vast amounts of land. The territory would also provide more room for the increasing population along the East Coast. Those who supported American Indian removal policies believed that the territory was the perfect place to relocate eastern American Indian tribes to.
