At the constitutional convention in 1787 the 3rd/fifth compromise was made why
The Three-Fifths Compromise, not the Third/Fifth Compromise, was made at the Constitutional Convention in 1787. This compromise addressed the issue of how enslaved individuals would be counted when determining a state's population for representation purposes in the House of Representatives and for taxation.
Southern states wanted to count enslaved individuals as part of their total population, which would increase their representation in Congress. Northern states, on the other hand, argued that if enslaved individuals were not considered citizens with rights, they should not be counted for representation either.
The compromise reached was that each enslaved individual would be counted as three-fifths of a person for representation and taxation purposes. This compromise appeased the Southern states as it provided them with more political influence through increased representation, while the Northern states still retained some power by not fully recognizing enslaved individuals as full citizens.
Ultimately, this compromise was a reflection of the deeply entrenched institution of slavery in the United States at the time and the complex political dynamics between the Northern and Southern states.
