A map of California, the Utah Territory, and the New Mexico Territory in 1850 showing the effect of the Compromise of 1850, a series of bills intending to settle the issue of slavery and abolition raised in the territories after the Mexican-American War (1846-1848). The map shows California as admitted to the Union as a Free State by the Compromise of 1850, and the territories of Utah and New Mexico where slavery was neither expressly allowed nor expressly prohibited by the compromise.
