More territories further west were now asking for admittance as states and again the argument arose as to whether these should by designated slave or free. Congressman David Wilmot of Pennsylvania introduced legislation stipulation that no new territories would by admitted as slave states. The "Wilmot Proviso" failed, but the debate rekindled vehement arguments in and out of Congress. The statesman Henry Clay engineered another compromise where California was admitted as a slave state, the territories of New Mexico and Utah were created without reference to the "Wilmot Proviso," and slavery was abolished in the District of Columbia. This legislation also included an act that addressed the return of fugitive slaves. This portion of the Compromise of 1850 Is referred to as The Fugitive Slave Act.
