The Constitution is a foundational legal document that outlines the principles and framework of a government. It establishes the structure, functions, and limits of government powers while protecting the rights of individuals. In many countries, the Constitution serves as the supreme law, guiding the legal system and ensuring justice. In the United States, the Constitution was adopted in 1787 and has been amended several times. It includes the Bill of Rights, which guarantees essential freedoms such as speech, religion, and assembly. The Constitution is vital for maintaining democracy and the rule of law.
