Three-fifths compromise, compromise agreement between delegates from the Northern and the Southern states at the United States Constitutional Convention (1787) that three-fifths of the slave population would be counted for determining direct taxation and representation in the House of Representatives.
Explanation:
this was made due to disputes over the idea that slaves could count for a states overall population, and if that was the case several southern states would have a large influence due to a large population of slaves. hence the agreement that a slave could only count for 3/5th of a man, reducing the overall influence/'population' of the southern states.
Answer: The Kansas-Nebraska Act of 1854 was a huge catalyst in sending the nation to the Civil War. This act reversed the Missouri Compromise and allowed slavery in the remainder of the original areas of the Louisiana Purchase. The balance of power shifted in the government and across the land.
