There were several, but I bet the one you're thinking of was slavery.
Representation in Congress
Interstate compacts were formed to settle regional issues. States have to acquire the consent of Congress in order to form a compact.
The delegates settled on a federal form of government instead of a system in which power was not divided between state and national government because they believed that it provided for a much stronger national government with a chief executive (the president), courts, and taxing powers.
Created the U.S. ConstitutionThe 55 delegates to the Constitutional Convention created the U.S. Constitution. On the final day of the convention, September 17, 1787, thirty eight of them signed the Constitution. The Constitution went into effect the next year, after it was ratified by nine states. The key pieces included the checks and balances and separation of powers: * Between the federal and state governments (and later the Bill of Rights asserted individual rights) * Within the federal government powers were split between executive, legislative, and judicial branches * Within the bicameral legislative branch powers were split between the House of Representatives, in which the representatives were apportioned according to each state's population, and the Senate, in which each state would have two senators. Unlike the Articles of Confederation, the national government can levy taxes directly onto citizens and industries.

Representation in Congress
dumb stuff
delegates at the constitutional convention of 1787 agreed to the three-fiths compromise as a way slaves were counted in determining a state's congressional delegation.
The Constitutional Convention exceeded its authority in writing a new Constitution and it was feared that if deliberations on a new Constitution were to be found out, the Convention would be dissolved. The Convention was supposed to work out amendments to the Articles of Confederation that would keep that document in effect but improve on its inherent weaknesses. It was soon apparent to the delegates that saving the Articles of Confederation by amendment was hopeless, so they began to create a new form of government entirely. This was a task, the delegates had no authority to do.
