Answer:
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.
Third parties influence the government by, by introducing new ideas and changing the outcome of certain elections.
