Transcript
The Compromise of 1850 was a series of measures passed by the U.S. Congress in an effort to settle regional disagreements over the state of American slavery.
The conflict involved the admission of new states and territories to the U.S.—and, more specifically, whether they would be admitted as “free” or “slave” states.
When California was presented for statehood as a free state, the proslavery coalition argued that the federal government shouldn’t be able to determine a new state’s laws regarding slavery.
Instead, they believed states should vote on their stance using a concept called “popular sovereignty.”
Proposed by Kentucky Senator Henry Clay, the Compromise of 1850 was an attempt to settle several outstanding slavery issues and prevent dissolution of the Union.
California was successfully admitted to the Union with its laws against slavery untouched, but Texas agreed to cede lands that would become New Mexico and Utah, where laws about slavery were left to be decided by the settlers living there.
The Compromise of 1850 also introduced a new and stronger Fugitive Slave Act—a law almost unanimously hated by Northerners—which obligated the federal government to aid in the recapture of liberated Black people and criminalized free people who aided the escape of the formerly enslaved.
In the long term, this unsettling “compromise” did little but sow the seeds of future American discord. The gap between Northerners and Southerners, and those living in “free” or “slave” states, was widening—and soon would lead to the start of the Civil War.
