Empires are large political entities that are typically composed of multiple nations, cultures, and people. The term 'REALMS' is often used to refer to empires, as it implies a certain level of sovereignty and authority over the lands and people within its borders. Empires have existed throughout history, from the ancient empires of Egypt and Mesopotamia to the modern-day empires of the United States and China. Empires have been both powerful and influential, and have shaped the course of history in many ways.
