MISSOURI COMPROMISE, a term given to a compromise under an act of Congress passed in February, 1821, at which time Missouri was admitted into the Union as a slave State, declaring that all territory W. of Missouri and N. of lat. 36° 30′ (the S. boundary of Missouri) should forever be free from slavery. This compromise was virtually repealed in 1854, when territorial governments were established for Kansas and Nebraska.
