The Compromise of 1850 was a set of five legislative measures enacted by the United States Congress to address the growing tensions between free and slave states in the years leading up to the Civil War. This compromise aimed to create a delicate balance between North and South by admitting California as a free state while allowing popular sovereignty in the territories acquired from Mexico, effectively allowing new states to decide their own stance on slavery. It also included the controversial Fugitive Slave Act, which mandated that escaped slaves be returned to their owners, intensifying sectional conflict.
