The 'Despotate of Morea' (
Greek: 'Δεσποτάτο του Μυστρά') was a province of the
Byzantine Empire which existed between the mid-
14th and mid-
15th centuries. Its territory varied in size during its 100 years of existence but eventually grew to take in almost all the southern
Greek Peloponnese peninsula, which at this time was called the
Morea. It was usually ruled by the current
Byzantine emperor's heir, who was given the title of ''despot'' or ''despoinis'' (in this context it should not be confused with
despotism). Its capital was the fortified city of
Mystras, near ancient
Sparta, which became an important centre of Byzantine culture and power.
The
Byzantine Despotate of Morea was carved out of territory seized from the
Frankish Principality of Achaea. This itself had been carved out of former Byzantine territory following the
Fourth Crusade (
1204). In
1259, the Principality's ruler
Guillaume II de Villehardouin lost the
Battle of Pelagonia against the Byzantine Emperor
Michael VIII Palaeologus. Guillaume was forced to ransom himself by giving up most of the eastern part of Morea and his newly built strongholds. The surrendered territory became the nucleus of the Despotate of Morea.
A later Byzantine emperor,
John VI Cantacuzenus, reorganized the territory in the mid-
14th century to establish it as an
appanage for his son
Manuel Cantacuzenus. The rival
Palaeologus dynasty seized the Morea after Manuel's death in
1380, with
Theodore I Palaeologus becoming the new despot of Morea in
1383. Theodore ruled it until
1407, consolidating Byzantine rule and coming to terms with his more powerful neighbours – particularly the expansionist
Ottoman Empire, whose
suzerainty he recognised. He also sought to reinvigorate the local economy by inviting
Albanians to settle in the territory.
As Latin power on the Peloponnese waned during the
15th century, the Despotate of Morea expanded to incorporate the entire peninsula. However, in
1446 the Ottoman Sultan
Murad II destroyed the Byzantine defences on the
Isthmus of Corinth. His attack opened the peninsula to invasion, though Murad died before he could exploit this. His successor
Mehmed II "the Conqueror" captured the Byzantine capital
Constantinople in
1453 and seven years later overran the Despotate of Morea, destroying the last European fragment of the Byzantine Empire.
