The Adams
Onis Treaty is named after the men who negotiated the agreement: John
Quincy Adams, Secretary of State of the United States, and Don Luis de
Onís (1762–1827), the Spanish minister in America.
The
Adams-Onis Treaty between the United States and Spain concluded all
controversies regarding Spain's claims to Florida. Signed in Washington
DC on February 22, 1819, by John Quincy Adams, the American secretary of state, and Luis de Onis, the Spanish minister, the treaty had three main effects.
All Spanish claims to East Florida were abandoned and the territory ceded to the United States,
The de facto control of West Florida, which had been in American hands since Andrew Jackson had established the American presence in 1818, was recognized, and
a firm delineation of the border between the Louisiana Purchase and the remaining Spanish claims in North America was settled, beginning with the Sabine River between Texas and Louisiana.
The
United States assumed the claims of its citizens against Spain, up to
$5 million, and Pinckney's Treaty of 1795 was continued to the extent
that it did not conflict. That should help you out
