The result of all this was a nationwide economic downturn that, rightly or not, was blamed on ruinous policies enacted by democratically-elected legislatures. In 1787, political dissatisfaction with the economic situation led to a convention convened in Philadelphia to remedy this state of affairs. The new Constitution it proposed, addressed debtor relief laws with the Contracts Clause of Article I, Section 10, which barred states from "impairing the obligation of contracts." To address the problems of interstate trade barriers and the ability to enter into trade agreements, it included the Commerce Clause, which grants Congress the power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes." Moving the power to regulate interstate commerce to Congress would enable the creation of a free trade zone among the several states; removing the power to regulate international trade from the states would enable the president to negotiate, and Congress to approve, treaties to open foreign markets to American-made goods. The international commerce power also gave Congress the power to abolish the slave trade with other nations, which it did effective on January 1, 1808, the very earliest date allowed by the Constitution.
