Compromise of 1850, is the right answer.
In September 1850 the Congress of the United States passed a set of five different bills that defused a legislative dispute between free and slave states on the standing of regions gained in the Mexican–American War, this set of bills came to be known as the Compromise of 1850. This compromise also set the western and northern boundaries of Texas and incorporated prerequisites approaching fugitive slaves and the slave trade.
