Theodore II Palaiologos

Theodore II Palaiologos or Palaeologus (Greek: Θεόδωρος Β΄ Παλαιολόγος, Theodōros II Palaiologos) (c. 1396 – 21 June 1448) was Despot in the Morea from 1407 to 1443 and in Selymbria from then until his death.

Theodore II Palaiologos was a son of the Eastern Roman Emperor Manuel II Palaiologos and his wife Helena Dragaš. His maternal grandfather was the Serb prince Constantine Dragaš. His brothers included emperors John VIII Palaiologos and Constantine XI Palaiologos, as well as Demetrios Palaiologos and Thomas Palaiologos, despots in the Despotate of Morea, and Andronikos Palaiologos, despot in Thessalonica.

When Theodore was a little over ten years old, his father proclaimed him a despot (despotēs) and appointed him to govern Morea after the death of his uncle Theodore I Palaiologos in 1407. The nobleman Nicholas Eudaimonoioannes was appointed as his tutor and regent until he came of age. The first period of his rule was a time of war against the Latin states in Greece for the unification of Morea. Theodore II's enemies in that period included the Republic of Venice, which sent troops to impede his attempt to conquer Patras. During Theodore's minority, his father Emperor Manuel II stayed in Morea and supervised its administration and defense, rebuilding the Hexamilion wall across the Isthmus of Corinth.
