Constitutional Convention and Ratification, 1787–1789
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. Under the reformed federal system, many of the responsibilities for foreign affairs fell under the authority of an executive branch, although important powers, such as treaty ratification, remained the responsibility of the legislative branch. After the necessary number of state ratifications, the Constitution came into effect in 1789 and has served as the basis of the United States Government ever since.
