what differences between the thirteen states made compromise necessary?

The differences between the thirteen states that made compromise necessary were mainly related to population size, representation, economic interests, and the issue of slavery. Large states wanted representation based on population, while smaller states wanted equal representation regardless of size. These conflicting views threatened the formation of a workable national government. Additionally, there were disputes over how slaves would be counted for representation and taxation, and differing views on regulating commerce, including the slave trade. These differences led to several important compromises at the Constitutional Convention, such as the Great Compromise (bicameral legislature with proportional representation in one house and equal in the other), the Three-Fifths Compromise (counting slaves as three-fifths of a person for representation), the Commerce Compromise (federal control over commerce but a delay on regulating the slave trade), and the Electoral College Compromise (electing the president through electors) to balance the interests of various states and regions.
