Ilia Colceag (fl. before 1710 1743) was a Moldavian mercenary and military commander, in the Ottoman and Russian Empire. He entered the Ottoman army and was first posted in Bosnia. Here, he converted to Islam and took the name of Hussein. He distinguished himself during the Russo-Turkish War of 1710/11 being promoted bölükba . In 1717 Sultan Ahmed III awarded him the title of pasha and named him commander of the Khotyn Fortress. Colceag kept this position for 22 years. In the Turkish historiography he is also known as Kolchak-Pasha. In 1734 (according to other sources 1736) he was appointed vizier, but held this position only for a short time. During the Russo-Turkish War of 1735 1739, Colceag was appointed commander in chief of the Ottoman armed forces of the Moldavian front. He did not see any major action, as the main battles were fought mainly on the Crimean peninsula. However, in 1738, when the main hostilities moved to the Southern Bug, the command of the Ottoman army was taken over by Veli-Pa a while Colceag kept his position of commander of the Khotyn Fortress.
