Person who rules in greek?

In Greek, the term for a ruler is "ἄρχων" (archon), which historically referred to a chief magistrate or leader in ancient Athens. Additionally, the Word "βασιλεὺς" (basileus) was used for kings or sovereigns. Both terms reflect different forms of governance in ancient Greek society, with "archon" often associated with democratic roles and "basileus" linked to monarchy.
