Which issue brought about the need for a compromise measure in 1850

The Compromise of 1850 was a package of five separate bills passed by the United States Congress in September 1850 that defused a political confrontation between slave and free states on the status of territories acquired in the Mexican–American War. It also set Texas's western and northern borders and included provisions addressing fugitive slaves and the slave trade. The compromise was brokered by Whig senator Henry Clay and Democratic senator Stephen Douglas with the support of President Millard Fillmore.
