History lesson: what is the 3/5 Compromise

I had not heard the term, “3/5 Compromise” since history class my freshman year of college, until I read the letter that Aaron McGruder, the creator of the popular comic strip and animated TV show, “Boondocks,” wrote in response to the claim that they said that President Obama was not black, a claim that he denies.  I had to read up on exactly what the 3/5 compromise was, and thought you might be interested.

The Three-Fifths Compromise was a compromise between Southern and Northern states reached during the Philadelphia Convention of 1787 in which three-fifths of the population of slaves would be counted for enumeration purposes regarding both the distribution of taxes and the apportionment of the members of the United States House of Representatives.  

Delegates opposed to slavery generally wished to count only the free inhabitants of each state. Delegates supportive of slavery, on the other hand, generally wanted to count slaves at their actual numbers. Since slaves could not vote, slaveholders would thus have the benefit of increased representation in the House and the Electoral College; taxation was only a secondary issue. The final compromise of counting "all other persons" as only three-fifths of their actual numbers reduced the power of the slave states relative to the original southern proposals, but is still generally credited with giving the pro-slavery forces disproportionate political power in the U.S. government from the establishment of the Constitution until the Civil War. 

The three-fifths compromise is found in Article 1, Section 2, Paragraph 3 of the United States Constitution:

Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons.

Following the Civil War and the abolition of slavery by the Thirteenth Amendment to the United States Constitution (1865), the three-fifths clause was rendered moot. Section 2 of the Fourteenth Amendment to the United States Constitution (1868) later superseded Article 1, Section 2, Clause 3. It specifically states that "Representatives shall be apportioned ...counting the whole number of persons in each State, excluding Indians not taxed..."
