Politarch (Greek: πολιτάρχης) was a Hellenistic and Roman-era Macedonian title for an elected governor (archon) of a city (polis). The term had been already attested in the (Acts of the Apostles 17:6,8) concerning Thessalonica, as well in modern archaeology. The institution is called Politarchate and Ptoliarchos appears in a poetic epigram. The first evidence of the title is dated to the reign of Perseus[1] [2][3] in Amphipolis, where the king with two politarchs honoured Artemis Tauropolos after a Thracian campaign.
The title was also used for the local commissioners of the Greek provisional government during the Greek War of Independence.
