Answer: Because each state was looking out for its personal interests in regard to representation in Congress.
Details:
The Great Compromise and the Three-Fifths Compromise both focused on the representation of states in Congress. Both of these compromises were devised during the United States Constitutional Convention in 1787.
The Great Compromise resolved a dispute between small population states and large population states. The large population states wanted representation in Congress to be based on a state's population size. The smaller states feared this would lead to unchecked dominance by the big states; they wanted all states to receive the same amount of representation. The Great Compromise created a bicameral (two-chamber) legislature. Representation in the House of Representatives would be based on population. In the Senate, all states would have the same amount of representation, by two Senators.
The Three-Fifths Compromise was a way of accounting (somewhat) for the population of slaves in states that permitted slavery. For taxation and representation purposes, the question was whether slaves should count in the population figures. (They were not considered voting citizens at that time.) The Three-Fifths Compromise said that three out of every five slaves could be counted when determining a state's population size for determining how many seats that state would receive in the House of Representatives.
The Stamp Act was passed on March 22, 1765, leading to an uproar in the colonies over an issue that was to be a major cause of the Revolution: taxation without representation. Enacted in November 1765, the controversial act forced colonists to buy a British stamp for every official document they obtained.
The election of 1866 gave them control of the two places of congress. The 1866 races were an unequivocal occasion in the early Reconstruction time, in which President Andrew Johnson went head to head against the Radical Republicans in an intense disagreement about whether Reconstruction ought to be permissive or brutal toward the vanquished South.
After the war, the Allies rescinded Japanese pre-war annexations such as Manchuria, and Korea became independent. The Philippines and Guam were returned to the United States. Burma, Malaya, and Singapore were returned to Britain and French Indo-China back to France.
While the Romans may not have contributed as much to the field of philosophy as the ancient Greeks, they were able to expand on many previously existing schools of thought. One of these areas is known as Stoicism.
