USA HISTORY

Detailed explanation-1: -The war began because a compromise did not exist that could solve the difference between the free and slave states regarding the power of the national government to prohibit slavery in territories that had not yet become states.

Detailed explanation-2: -For more than 80 years, people in the Northern and Southern states had been debating the issues that ultimately led to war: economic policies and practices, cultural values, the extent and reach of the Federal government, and, most importantly, the role of slavery within American society.

Detailed explanation-3: -Slavery played the central role during the American Civil War.
