A polemarch was a senior military title in various ancient Greek city states (poleis). The title is derived from the words polemos (war) and archon and translates as "warleader" or "warlord". The name indicates that the polemarch's original function was to command the army; presumably the office was created to take over this function from the king. The title held a high position in Athenian society, alongside the archon eponymos and the archon basileus. In Athens the polemarch was the commander-in-chief of the armed forces of the city-state.
