Tennessee

Washington, Jefferson, Madison, Monroe

The Southern states wanted to count all of their slaves for determining representation. The 3/5 compromise gave Virginia in particular and the Carolinas more seats in congress from the get go. The 3/5 compromise is directly responsible for all those Virginia presidents.

The Constitution banned the Slave Trade, but by the time that ban went into effect, there wasn't a need for importing human labor, since children born to slave women were slaves.

There was no real push to eliminate chattel slavery in setting up the house of representative or the Constitution.
