Theodore Philes (Greek: Θεόδωρος Φιλῆς) was a Byzantine nobleman and governor of Thessalonica in the mid-13th century.
This post, apparently designated with the title of "praetor", entailed a very wide remit, encompassing military, fiscal and judicial authority over the lands and cities of Macedonia that were in Nicaean hands.
[2] During his governorship, Philes slighted the Nicaean heir-apparent, Theodore II Laskaris, who now became his avowed enemy.
When Theodore II succeeded to the throne in 1254, Philes and another leading noble, Constantine Strategopoulos, were blinded at the emperor's orders for lèse-majesté.
[4] Consequently Philes and his family became supporters of the aristocratic opposition around Michael Palaiologos, and after Theodore II's death in 1258 supported him in his bid for control of the empire against the regent, George Mouzalon.
