The Debate
In the North
The South
 Wanted to ban slavery in
 Worried that free states
Missouri
 Maine, which was a part of
Massachusetts, wanted
statehood
would have the majority in
Congress
 Felt that the Constitution did
not give Congress the power
to ban slavery
The Compromise, 1820
 Henry Clay, the Speaker of the House, saw an
opportunity for compromise.
 He suggested admitting Maine as a free state and
Missouri as a slave state, keeping the balance between
the number of slave and free states, and the balance of
power in Congress
 The Missouri Compromise also banned slavery in the
Louisiana Territory, north of the 36° 30’ parallel
 Thomas Jefferson, at 80, worried that this might
destroy the country
Manifest Destiny
 The belief that America is destined to stretch across
the continent from the Atlantic Ocean to the Pacific
Ocean
 “Our manifest destiny [is] to overspread and possess
the whole of the continent which Providence (God)
has given us for the development of the great
experiment of liberty and.....self-government.” John
O’Sullivan, United States Magazine and Democratic
Review
 Manifest = clear, obvious
The Oregon Trail
 By the 1840’s thousands of Americans had moved into
the Oregon Territory.
 Presidential hopeful, James K. Polk, used the Oregon
Territory as a platform for election. His slogan ‘Fiftyfour forty or fight!’ referred to the 54° 40’ N latitude.
This was the northern most boundary of the Oregon
Territory.
 Rather than fight, Great Britain and the U.S. settled for
the 49th parallel as the northern boundary in 1846.
 The border stands today between the U.S. & Canada.
