How was the constitution affected by slavery?

Explanation:

States with large slave populations ended up with more power both in Congress and in the Supreme Court, which undercut the power of abolition states.

The most democratic aspects of the Constitution included a compromise measure that gave the federal government power to regulate commerce, but only at the price of giving unequal power to slave states.

Congress was forbidden from passing export duties, when most of the value that United States exported was slave-grown commodities.

It resulted in the illegal kidnapping and return to slavery of thousands of free blacks.
