Boeotarch (Greek: Βοιωτάρχης, Boiotarches) was the title of the chief officers of the Boeotian Confederacy, founded in 379 BC after a rebellion freed the cities of Boeotia from Spartan dominance.
As the largest city of the region, Thebes generally elected four of the Boeotarchs, while the other three represented outlying districts.
The function of the Boeotarchs were roughly equivalent to that of the Athenian strategos, acting as both political leaders and generals in battle.
And indeed, many other political, military, and judicial offices in the Boeotian League were copied from the Athenian model.
[2] The most famous individuals to hold the office were Epaminondas and Pelopidas, who led Thebes to hegemonic status over Greece in the middle of the 4th century BC ("Theban hegemony").
