The Greek Constitution is the fundamental legal document that outlines the structure and principles of the Hellenic Republic. It was first adopted in 1822 and has undergone several revisions, with the current version established in 1975. The Constitution defines the rights of citizens, the organization of government, and the separation of powers among the executive, legislative, and judicial branches. Key features of the Greek Constitution include the protection of individual rights, the establishment of a parliamentary system, and provisions for local governance. It serves as the foundation for Greek law and ensures that the government operates within a framework of democracy and rule of law.
