Ancient institutions refer to established organizations or systems that played a significant role in early societies. These include governments, religious organizations, and educational systems that helped maintain order, provide services, and transmit knowledge. They often shaped cultural practices and social norms, influencing how communities functioned. Many ancient institutions were tied to specific civilizations, such as the Roman Senate or the Egyptian priesthood. These institutions often had lasting impacts, laying the groundwork for modern systems of governance, law, and education. Their structures and functions can still be seen in contemporary societies around the world.
