The First Amendment is part of America's Bill of Rights. The Bill of Rights was added to the Constitution. It is the first 10 amendments. Amendments are rights that we didn't add to the constitution. There were two groups, The Federalists and Anti-Federalists. The Federalists wanted the Constitution. Anti-Federalists' wanted amendments added to the Constitution. So they made the Bill of Rights. They knew that in the future we would have to add more amendments.
The Constitution was made on September 17, 1787. It was ratified on June 21, 1788. This document is the supreme law of the U.S. At first it had seven articles. The first 3 articles talk about separation of powers. The separation of powers is where the federal government has 3 divisions: the legislative which has the congress, executive, the President and the judiciary, consists of the Supreme Court and other federal courts. The Constitution has been amended 27 times since its ratification. The first 10 amendments are called the Bill of Rights.
The first amendment has survived more than two-hundred years, without being modified. The finite history of the first amendment proves its significance and role in America. It prohibits the establishment of a nation-wide religion, and guarantees freedom of worship, speech, press and to peaceable assembly. Without this Amendment, a religious minority could be mistreated, the government would set up a religion; protesters could be harmed or jailed and the press would not be able to bring us facts about the government. The first amendment was created by James Madison in 1781, he didn't want to repeat history like with Great Britain. Americans were grateful for this amendments because they were able to express themselves freely about what they like and dislike about the government.
The First Amendment was created because the founding fathers wanted to guarantee that American's basic civil rights would not be threatened by the government.
