In 1776, Thomas Jefferson penned the American Declaration of Independence.
On July 4, 1776, the United States Congress approved the Declaration of Independence. Its primary author, Thomas Jefferson, wrote the Declaration as a formal explanation of why Congress had voted on July 2 to declare independence from Great Britain, more than a year after the outbreak of the American Revolutionary War, and as a statement announcing that the thirteen American Colonies were no longer a part of the British Empire. Congress issued the Declaration of Independence in several forms. It was initially published as a printed broadsheet that was widely distributed and read to the public.
Philosophically, the Declaration stressed two themes: individual rights and the right of revolution. These ideas became widely held by Americans and spread internationally as well, influencing in particular the French Revolution.
The Constitution of the United States of America (1787) and Bill of Rights (1791)
The Bill of Rights of the US Constitution protects basic freedoms of United States citizens.
Written during the summer of 1787 in Philadelphia, the Constitution of the United States of America is the fundamental law of the US federal system of government and the landmark document of the Western world. It is the oldest written national constitution in use and defines the principal organs of government and their jurisdictions and the basic rights of citizens.
The first ten amendments to the Constitution—the Bill of Rights—came into effect on December 15, 1791, limiting the powers of the federal government of the United States and protecting the rights of all citizens, residents and visitors in American territory.
The Bill of Rights protects freedom of speech, freedom of religion, the right to keep and bear arms, the freedom of assembly and the freedom to petition. It also prohibits unreasonable search and seizure, cruel and unusual punishment and compelled self-incrimination. Among the legal protections it affords, the Bill of Rights prohibits Congress from making any law respecting establishment of religion and prohibits the federal government from depriving any person of life, liberty or property without due process of law. In federal criminal cases it requires indictment by a grand jury for any capital offense, or infamous crime, guarantees a speedy public trial with an impartial jury in the district in which the crime occurred, and prohibits double jeopardy.
