Compromise of 1850
The Compromise of 1850 was a package of five laws passed by Congress to settle disputes over slavery in territory won from Mexico. It admitted California as a free state and enacted a stricter Fugitive Slave Act, delaying but not preventing sectional conflict.
Victory in the Mexican-American War brought the United States vast new territory and reopened the question of whether slavery would expand into it. The Wilmot Proviso, which would have barred slavery from all land acquired from Mexico, passed the House repeatedly but died in the Senate, leaving the issue unresolved and the sectional balance in Congress in doubt when California applied for admission as a free state.
Henry Clay proposed an omnibus bill, and after it failed, Stephen A. Douglas guided its provisions through Congress as five separate measures. The package admitted California as a free state, organized the New Mexico and Utah territories under popular sovereignty so their settlers would decide the question themselves, settled the Texas–New Mexico boundary in exchange for federal assumption of Texas's debt, abolished the slave trade (though not slavery itself) in the District of Columbia, and enacted a far stricter Fugitive Slave Act.
The Fugitive Slave Act proved the most explosive element. It compelled citizens in free states to assist in capturing suspected fugitives, denied the accused a jury trial and the right to testify, and paid commissioners more for ruling in favor of claimants. Northern outrage produced personal liberty laws, open resistance, and a surge of antislavery sentiment that Harriet Beecher Stowe channeled into Uncle Tom's Cabin in 1852. The compromise bought roughly a decade of uneasy peace, but the Kansas-Nebraska Act of 1854 and the collapse of the Second Party System soon undid it.
