The last hope of the Byzantine, the monarch of Morea.

 In 1259, when the Byzantine Empire could not find its old capital yet... Michael VIII Palaeologus, the emperor of the Nicaean Empire, began the war of conquering Morea, or the current Peloponnesus. At that time, Morea was still in Latin hands, and the most important of the many Latin rulers was Guillaume II de Villehardouin (1245-1287). In 1249, exactly 10 years before the conquest war of the Byzantine Empire, Guillaume built a new city in the southern part of Morea, the city of Mystra (or Mystras. Mistra was located on the hill of Tigetus, 6km west of the ancient Sparta.(Of course, it was easy to defend.) In 1259, 10 years after the construction of the Mistra, the Byzantine Empire troops attacked the Morea region. Eventually, Guillaume's army was defeated in the Battle of Pelagonia (1259), and Guillaume also became a prisoner of the imperial army. Instead of saving Guillaume's life and releasing him, Emperor Michael VIII made him pay for the newly built fortress (Mistra) and the eastern Morea region, his territory. Later, the Byzantine Empire eventually occupied about a quarter of Morea's total, and the emperor dispatched his younger brother Constantine to command Malvasia and Sparta. After Guillaume's death, the remaining power of Franks and the remaining territory of Morea owned by Angevins became all Byzantine, further expanding the Byzantine power in the Morea region. In 1261, the Byzantine Empire finally recaptured Constantinople and revived. At one time, conquering most of the Balkan Peninsula, the empire seemed to be looking for its old appearance. However, as has been the case before, the leadership continued to divide again, and the empire was in jeopardy again as the rule of incompetent emperors continued. Even when the empire as a whole was weakening, the Byzantine Morea steadily grew around Mistra. So in 1349, just 100 years after the city was built, Emperor Johannes VI Cantacuzenus dispatched his son Manuel as the first monarch of Morea. At last, Morea became a monarch with Mistra as the capital, not Sokju. Finally... a small but new hope of being the monarch of Morea was created in the decaying Byzantine Empire.
