The addition of the Louisiana Purchase to the United
States was critical not only for the future of the Native
Americans but for that of African slavery as well. As
Native Americans were forcibly moved to the newer
lands, their old lands in the South were increasingly
developed as plantations run with slave labor. The
national debate about the expansion of slavery would
have taken a very different form had the Louisiana
Territory not been available.
