a. Spain had been worn
out by the Peninsular war in Europe and needed to rebuild its authority and presence
in its colonies. So the Spain and US signed an Admas – Onis treaty which set
out a boundary between the New Spain (now Mexico) and US.
b. Spanish
minister Do Luis de Onis and US Secretary of State John Quincy Adams signed the
Florida Purchase Treaty. Spain agrees to surrender the remainder of its old
province of Florida to the United States.
c. The
Seminoles and runaway slaves from parts of
America often attacked the Georgia landowners and then fled back into
Florida. To end these Seminole raids, General Andrew Jackson and his army came
to Florida in 1817 and signed a treaty with the Florida and US.
