The Constitutional Convention happened in 1787 in Philadelphia. The intent of the convention was to establish the U.S. Constitution. Each state, regardless of its number of delegates had a single vote. Thirty-nine of the fifty-five delegates supported the adoption of the new Constitution. Rhode Island was against the Convention and therefore sent no representation.
