Which of these was not a key difference between northern and southern states at the constitutional convention?
wanting to protect states' interests vs. a government with strict rules
having more, larger cities vs. having fewer, smaller cities

The correct answer is D) Having many enslaved people vs. using less enslaved labor.

The option that was not a key difference between Northern and Southern states at the Constitutional Convention was "Having many enslaved people vs. using less enslaved labor."

Without a doubt, there were many differences between the Northern and the Southern states by the time the Constitutional Convention was held in 1787. The purpose of this Constitutional Convention was to modify the Articles of the Confederation, established after the victory over England in the Revolutionary War.

The Constitutional Convention was held from May 14 to September 17, 1787, in the city of Philadelphia, where the delegates proposed a series of plans to create the new form of government and unite the colonies. One of the more problematic issues in the discussions was the topic of slavery.
