Constitutional Convention At the Constitutional Convention held in Philadelphia in 1787, the delegates created the U.S. Constitution to replace the Articles of Conferderation.
The Constitutional Convention in Philadelphia met between May and September of 1787 to address the problems of the weak central government that existed under the Articles of Confederation. The United States Constitution that emerged from the convention established a federal government with more specific powers, including those related to conducting relations with foreign governments.
From https://history.state.gov/milestones/1784-1800/convention-and-ratification The Conneticut Compromisewas an agreement that large and small states reached during the Constitutional Convention of 1787 that in part defined the legislative structure and representation that each state would have under the United States
On July 16, 1787, a plan proposed byRoger ShermanandOliver Ellsworth, Connecticut’s delegates to the Constitutional Convention, established a two-house legislature. The Great Compromise, or Connecticut Compromise as it is often called, proposed a solution to the heated debate between larger and smaller states over their representation in the newly proposed Senate. The larger states believed that representation should be based proportionally on the contributions each state made to the nation’s finances and defense, and the smaller states believed that the only fair plan was one of equal representation. The compromise proposed by Sherman and Ellsworth provided for a dual system of representation. In the House of Representatives each state’s number of seats would be in proportion to population. In the Senate, all states would have the same number of seats.
The 3/5 Compromise proposed the each slave would be counted as 3/5 of a person for the purpose of assigning taxes and representation in Congress. The 3/5 Compromise gave disproportinate political power to the Southern slave states.
The issue of how to count slaves split the delegates into two groups. The northerners regarded slaves as property who should receive no representation. Southerners demanded that Blacks be counted with whites. The compromise clearly reflected the strength of the pro-slavery forces at the convention. The “Three-fifths Compromise” allowed a state to count three fifths of each Black person in determining political representation in the House.
