Wilmot ProvisoThis is a bill that tried to prohibit slavery in the new territories in the Mexican Cession, but failed to pass in Congress.
Compromise of 1850John Quincy Adams, John C. Calhoun, and Henry Clay came up with this compromise in 1850 to keep the balance of free/slave states. The North liked it, because slave trade was abolished there and California was admitted as a free state. The South liked it, because the new territories could vote for slavery or against it and the Fugitive Slave Act was passed. The compromise was important, because it managed to keep both sides of the country satisfied
