In the mid-1860s the country of the United States of America faced a serious obstacle, the secession crisis. In the early 1800s, the United States faced a major topic of debate: slavery. The South supported slavery. They believed it was customary for lifestyle and religion. The North did not believe in slavery and wanted no part in owning another human being because they believed it was wrong and inhumane and that God did not approve of owning a slave. The Northern and Southern parts of America experienced the crises of the session very differently, with Northerners seeking to end slavery over a gradual period of time and Southerners demanding that the rights they possess derive to them from the U.S. Constitution and by states' rights that were given to them with the help of Southern leaders who were more responsible for the session's crisis than Northern leaders. The Civil War was a war between the Union and the Confederacy in the United States or between the North and the South. One of the main causes of the outbreak of the Civil War was slavery. In the book At the precipice, the Northern states and the Southern states experienced the crisis of secession very differently. Bowman explains why the South seceded from the union in hopes of preserving slavery, not losing products, and maintaining the rights given to them by the state and the Constitution. Bowman then explains how the Northern states want to abolish slavery and make the United States one again without Confederate countries, without trying to cause a civil war. The leaders of the Southern states were more responsible for the secession crisis because it was their intention to leave the union because the beliefs about religion, power, and goals they had as a confederacy were very different from those of the United States or the U.S..
