How Did the Bill of Rights Come to Be?

Learn more about the history and evolution of the first 10 amendments

In U.S. history classes, Americans learn that the first 10 amendments to the United States Constitution are called the Bill of Rights, which collectively guarantees individual liberties and prevents tyranny from the federal government. The First Amendment alone secures five of America’s most cherished freedoms: religion, speech, press, assembly, and petition of the government.

But these rights weren’t originally a part of the Constitution. After pressure from several states, the First Congress in 1789 voted to include them to help ensure that the document that defines how the United States is governed includes protections for individuals and limits on the federal government’s power. Get a closer look at the origins of the Bill of Rights with these facts.
