Theodosios III

From Wikipedia, the free encyclopedia

Theodosios III or Theodosius III (Greek: Θεοδόσιος Γ΄), was Byzantine Emperor from 715 to March 25, 717.

[edit] Life

Theodosios was a financial officer and tax collector in the southern portion of the theme of Opsikion. According to one theory he was the son of the former Emperor Tiberios III. When the thematic troops rebelled against Emperor Anastasios II, he was chosen as emperor. Theodosios did not readily accept this choice and according to the chronicler Theophanes the Confessor even attempted to hide in the forests near Adramyttium. Eventually he was found and was acclaimed emperor in May 715.

Theodosios and his troops immediately laid siege to Constantinople. Six months later, in November, they gained entry the city. Theodosios showed himself remarkably moderate in his treatment of his predecessor and his supporters. Through the intercession of Patriarch Germanos I of Constantinople Anastasios II was convinced to abdicate and become a monk in Thessalonica.

Little is known of Theodosios' short reign. He immediately faced an Arab invasion deep into Anatolia and the advance of the Arab fleet. In 716 he concluded a treaty with Kormesiy of Bulgaria favorable to the Bulgarians in effort to secure support against the Arab invasion. This policy paid off in 719, when they helped relieve the Second Arab siege of Constantinople.

In 717, the strategos of the Anatolic theme, Leo the Isaurian (the future Leo III), rebelled against Theodosios' rule in collusion with Artabasdos, the strategos of the Armeniac theme. Theodosios' son was captured by Leo in Nicomedia, and Theodosios chose to resign the throne on March 25, 717. He and his son subsequently entered the clergy.

By 729 Theodosios is believed to have become bishop of Ephesus. Modern historians however suspect the bishop was actually his son. Either way, this bishop was last recorded alive on July 24, 754, taking part in the iconoclastic Council of Hieria.
