During the early years of the U.S. republic, its vital southwestern quadrant - encompassing the modern-day states between South Carolina and Louisiana - experienced nearly unceasing conflict. In The Old Southwest, 1795-1830: Frontiers in Conflict, historians Thomas D. Clark and John D. W. Guice analyze the many disputes that resulted when the United States pushed aside a hundred thousand Indians and overtook the final vestiges of Spanish, French, and British presence in the wilderness. Leaders such as Andrew Jackson, who emerged during the Creek War, introduced new policies of Indian removal and state making, along with a decided willingness to let adventurous settlers open up the new territories as a part of the Manifest Destiny of a growing country.
