The delegates to the Constitutional Convention disagreed over the wisdom of listing specific rights within the U.S. Constitution, but members of the First Congress, fresh from the struggle against tyranny, insisted on the necessity of protecting individual liberties, including the freedoms of speech, religion and assembly. In 1789 they proposed twelve amendments to the original U.S. Constitution. Ten of these were swiftly ratified by the states and became known as the Bill of Rights. They form part of the bedrock of our national government.
