Slavery in the Territories
On August 8, 1846, Pennsylvania Democrat David Wilmot heightened tensions
between North and South by introducing an amendment to a military appropri-
ations bill proposing that “neither slavery nor involuntary servitude shall ever
exist” in any territory the United States might acquire as a result of the war with
Mexico. In strictly practical terms, the Wilmot Proviso meant that California, as
well as the territories of Utah and New Mexico, would be closed to slavery forever.
THE WILMOT PROVISO
The Wilmot Proviso divided Congress along regional
lines. Northerners, angry over the refusal of Southern congressmen to vote for
internal improvements, such as the building of
canals and roads, supported the proviso. They also
feared that adding slave territory would give slave
states more members in Congress and deny eco-
nomic opportunity to free workers.
Southerners, as expected, opposed the proviso,
which, some argued, raised complex constitutional
issues. Slaves were property, Southerners claimed,
and property was protected by the Constitution.
Laws like the Wilmot Proviso would undermine
such constitutional protections.
Many Southerners feared that if the Wilmot
Proviso became law, the inevitable addition of new
free states to the Union would shift the balance of
power permanently to the North. The House of
Representatives approved the proviso, but the
Senate rejected it. Congressman Alexander H.
Stephens of Georgia issued a dire prediction.
A PERSONAL VOICE ALEXANDER H. STEPHENS
“ The North is going to stick the Wilmot amendment to every appropriation and
then all the South will vote against any measure thus clogged. Finally a tremen-
dous struggle will take place and perhaps [President] Polk in starting one war
may find half a dozen on his hands. I tell you the prospect ahead is dark, cloudy,
thick and gloomy.

—quoted in The Coming of the Civil War
STATEHOOD FOR CALIFORNIA
As a result of the gold rush, California had
grown in population so quickly that it skipped the territorial phase of becoming
a state. In late 1849, California held a constitutional convention, adopted a state
constitution, elected a governor and a legislature, and applied to join the Union.
California’s new constitution forbade slavery, a fact that alarmed many
Southerners. They had assumed that because most of California lay south of the
Missouri Compromise line of 36˚30’, the state would be open to slavery. They had
hoped that the compromise, struck in 1820, would apply to new territories,
including California, which would have become a slave state.
General Zachary Taylor, who succeeded Polk as president
in 1849, supported California’s admission as a free state.
Moreover, he felt that the South could counter abolitionism
most effectively by leaving the slavery issue up to individual
territories rather than to Congress. Southerners, however,
saw this as a move to block slavery in the territories and as an
attack on the Southern way of life—and began to question
whether the South should remain in the Union.
