Leucosyri
Leucosyri, or Leucosyroi, also known as Leucosyrians or White Syrians, are an ancient tribe that existed in Anatolia. They were eventually hellenised. The name "Leucosyri" derived from the Greek name Λευκόσυροι or Λευκοσύριοι meaning White Syrians.
It has been believed that the Leucosyri lived in Pontus, Cappadocia, Cilicia and parts of central-west Asia Minor.
During the Mithridatic Wars, the Leucosyrians were recruited as mercenaries into the Pontic army to fight off the Roman army of Sulla and later Pompey.
