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.

The Battle of Marathon took place in 490 BC during the first Persian invasion of Greece. It was fought between the citizens of Athens, aided by Plataea, and a Persian force commanded by Datis and Artaphernes. The battle was the culmination of the first attempt by Persia, under King Darius I, to subjugate Greece. The Greek army inflicted a crushing defeat on the more numerous Persians, marking a turning point in the Greco-Persian Wars.
