Constantine Kalamanos or Coloman (Greek: Κωνσταντῖνος Καλαμανός; 1137/1145 – after 1173) also referred to as Doux of Cilcia,[1]was a Byzantine general and governor of Cilicia.
[2] In 1163, Emperor Manuel I Komnenos appointed Constantine governor of Cilicia, a province of the empire, whose fortresses had just been captured by the Armenian prince Thoros II.
After Bohemond's provocation, Constantine rushed with his troops, and Nur ad-Din Zengi, upon hearing the news, increased the siege to no avail.
However, Nur ad-Din Zengi was anxious not to offend the Byzantine Empire, and almost immediately released Constantine (1166), in exchange for one hundred and fifty pieces of silver.
[4] In 1170, Prince Mleh of Armenia invaded the Byzantine province of Cilicia with the help of Nur ad-Din Zengi, and took Mopsuestia, Adana, and Tarsus.
