When the Framers of the Constitution sent their handiwork out to the states for ratification in 1787, opponents denounced it. The new system of government, they argued, threatened to take away power from the states and the people and give it to the federal government. Many of these Anti-Federalists, as they were called, agreed to support ratification, though, in return for a promise that the new Congress would quickly add amendments protecting the people’s rights.
