What were the Greek men in charge of rebellions called?

The Greek men in charge of rebellions were often referred to as "demagogues" or "leaders." In the context of the ancient Greek city-states, particularly during the Classical period, these leaders could also be called "tyrants" if they seized power unconstitutionally, though the term had different connotations than it does today. Additionally, during specific uprisings, such as the Greek War of Independence, they were known as "captains" or "chieftains."
