A tomb found near Arzos dates back to the 4th century BC. Arzos was ruled by the Ottoman Empire until the Balkan Wars of 1913. After a brief period of Bulgarian rule between 1913 and 1919, it became part of Greece. As a result its Bulgarian and Turkish population was exchanged with Greek refugees, mainly from today's Turkey.
