had to be blasted away. Rock barriers were removed with an

One dramatic controversy that
unfolded during the Monroe
administration took place when the
Missouri Territory made application
to become a new state. Normally,
such applications were encouraged,
as a sign of the country’s progress and
further movement west. But there was
a fl y in the ointment with Missouri,
because it sought admission into the
Union as a slave state.
In 1819, the year Missouri applied
for statehood, the nation was evenly
split between slave and free states,
with 11 of each. It had become
important, even crucial, to both
Northerners and Southerners that a
balance of power between these two
elements be maintained in the U.S.
Senate, where neither would have a
majority that might allow one section
to direct policy over the other. It was
a tenuous balance, however, and one
that could not be maintained forever.
Five new slave states had already
been added to the United States
prior to 1820, but they were all in
the South—Kentucky, Tennessee,
Louisiana, Mississippi, and Alabama.
But in Missouri’s case the Northerners
held fi rm and refused to accept
a new slave state, especially one
located in the West. With Missouri’s
application, the door seemed ready
to open on slavery’s expansion across
the entire western region of the
Louisiana Territory, some 800,000
square miles (2 million sq. km) of
land. Northerners were convinced
that, if slavery were allowed to
expand in that region, there would
be no limit to its eventual reach. As
noted by historian Adrienne Koch, an
aged Thomas Jefferson, a slaveholder
himself, expressed immediate
concern over the possible expansion
of slavery into the West, writing in
a letter to a friend that the potential
