Although slavery effectively speeded up American agricultural growth, an increasing number of Americans, mostly from the North, began toquestion the principal of slavery and outlaw it in states established by the Compromise of 1812. During the 1860s, sectional conflict over slavery intensified as America gained new territories of California, Kansas, and Nebraska. In an attempt to compromise the dispute between the North and the South on whether new territories be recognized as free states, the Kansas and Nebraska Act was signed on May 30, 1854 to let the peoplewithin the territories to decide on the basis of popular sovereignty. Yet, this act solidified the opposite opinions of both sides, divided the nation even more, and directed it towardthe Civil War.
