Final answer:
The Three-Fifths Compromise was about how to count slaves for both legislative representation and taxation, allowing three-fifths of the enslaved population to be counted, delaying the end of the Atlantic slave trade to 1808, and avoiding the term 'slave' in the Constitution.
Step-by-step explanation:
The central issue of the Three-Fifths Compromise was how to count the enslaved population within the states when determining both representation in the legislature and the imposition of federal taxes.
The compromise, which was a major topic during the Philadelphia Convention of 1787, stipulated that three-fifths of the enslaved population would be included in population counts for apportionment of the members of the United States House of Representatives and for federal taxation purposes.
The compromise also addressed the Atlantic slave trade by determining that it would not be abolished before 1808, and it avoided the use of the term 'slave' in the Constitution, instead, the document referenced 'free persons' and 'all other persons.'
