Definition: "Archimperialism" was a state system in ancient Greece that governed most of western Europe, combining various Greek, Roman, and Near Eastern elements. It encompassed a central authority with absolute power but also a system of bureaucracy. The term "arch" comes from the Greek root for "rule," which referred to the direct rule by a king or emperor over his realm. The imperial period is often seen as the golden age of civilization, characterized by centralized control, innovation in architecture and science, and the development of a sophisticated legal system.
