Theodore Angelos (Greek: Θεόδωρος Ἄγγελος, romanized: Theodōros Angelos) was co-ruler of Thessaly from c. 1289 to his death in c. 1299.
Theodore was the third son of John I Doukas, ruler of Thessaly by his wife, who is only known by her monastic name Hypomone ("Patience").[1][2] When John died in or shortly before 1289, he was succeeded by Theodore's older brother Constantine, but Theodore served as his co-ruler. Initially, the two brothers were under the tutelage of Anna Palaiologina Kantakouzene as they were underage.[3] Awarded the title of sebastokrator from the Byzantine emperor in 1295, he was scheduled to marry the Armenian princess Theophano, daughter of King Leo II, but this project fell through.[2] He was defeated in battle by the Byzantine general Michael Doukas Glabas Tarchaneiotes, and died in c. 1299.[2]
