A constitution is a set of fundamental principles or established precedents that govern a country or organization. It outlines the structure of government, the rights of citizens, and the responsibilities of leaders. For example, the United States Constitution serves as the supreme law of the land, ensuring that all laws and actions align with its guidelines. In addition to defining government powers, a constitution often protects individual rights. This can include freedoms such as speech, religion, and assembly. By establishing these rights, a constitution helps maintain order and justice within society, ensuring that everyone is treated fairly under the law.
