First Seminole War 18171818
 The First Seminole War (1817–1818) began
over attempts by U.S. authorities to
recapture runaway black slaves living among
Seminole bands.
 Under General Andrew Jackson, U.S. military
forces invaded the area, scattering the
villagers, burning their towns, and seizing
Spanish-held Pensacola and St. Marks.
Convention of 1818
 The summary of the Convention of 1818
solved the boundary problems between the
UK and the United States. It also allowed
both nations to occupy the Oregon Country
as well as to establish settlements.
 The Convention of 1818 was also a major loss
of territory for the UK in North America.
Monroe Doctrine
 Proclamation in 1823 by President James Monroe. It
warned European nations not to get involved in
political matters in Central and South America. The
Doctrine was intended to show that the United States
was the only country that could influence such
political matters. Further, several countries in South
American had recently undergone revolutions against
their European colonial owners and ended up with
republican governments. The United States agreed
with their political philosophy and did not want to see
those newly free nations become European colonies
again.
Florida Purchased from
Spain
 The Territory of Florida was an organized
incorporated territory of the United States
that existed from March 30, 1822, until March
3, 1845, when it was admitted to the Union as
the State of Florida. Originally the Spanish
territory of La Florida, and later the provinces
of East and West Florida, it was ceded to the
United States as part of the 1819 Adams-Onís
Treaty.
Adams-Onis Treaty
 The Adams–Onís Treaty of 1819, also known as the
Transcontinental Treaty or the Purchase of Florida
or the Florida Treaty, was a treaty between the
United States and Spain in 1819 that gave Florida to
the U.S. and set out a boundary between the U.S.
and New Spain (now Mexico). It settled a standing
border dispute between the two countries and was
considered a triumph of American diplomacy.
Missouri Compromise 1820
 The Missouri Compromise was passed in
1820 between the pro-slavery and antislavery factions in the United States
Congress, involving primarily the regulation
of slavery in the western territories. It
prohibited slavery in the former Louisiana
Territory north of the parallel 36°30’ north
except within the boundaries of the
proposed state of Missouri.
“Era of Good Feeling”
 Monroe embarks on a lengthy, sixteen-week tour of
New England. In the absence of his major cabinet
appointees, Monroe uses the tour to foster a sense
of national unity through local political contact,
public appearances, and private meetings with
opposing Federalists. The tour gives birth to the
designation of Monroe's administration as the “Era
of Good Feelings.”
