 In the West, New Spain bordered the territory acquired by the U.S. in the Louisiana Purchase, but no clear boundary had been established between U.S. and Spanish territory.After taking office, Adams began negotiations with Luis de Onís, the Spanish minister to the United States, for the purchase of Florida and the settlement of a border between the U.S. and New Spain.The negotiations were interrupted by an escalation of the Seminole War, and in December 1818 Monroe ordered General Andrew Jackson to enter Florida and retaliate against Seminoles that had raided Georgia.
