What about the compromise of 1850 that made south happy?

The Compromise of 1850 included provisions that pleased the South, particularly the passage of the Fugitive Slave Act, which mandated that escaped slaves be returned to their owners and imposed penalties on those who helped them escape. Additionally, the compromise allowed California to enter the Union as a free state while leaving the status of slavery in the newly acquired territories of New Mexico and Utah to be determined by popular sovereignty, giving the South a chance to expand slavery into those areas. This balance aimed to appease Southern interests and maintain the Union amidst growing sectional tensions.
