Knowledge 1: Catherine Zaccaria
Catherine Zaccaria or Catherine Palaiologina (died 26 August 1462) was the daughter of the last Prince of Achaea, Centurione II Zaccaria.In September 1429 she was betrothed to the Byzantine Despot of the Morea Thomas Palaiologos, and married him in January 1430 at Mystras.She remained in the Morea as Thomas' consort ("basilissa") until the Ottoman conquest in 1460, after which she fled to the Venetian-held island of Corfu.There she died on 26 August 1462, being buried in the Monastery of Jason and Sosipatros.By her marriage with Thomas, she had four children, the sons Andreas and Manuel and the daughters Helena(wife of Lazar Branković of Serbia) and Zoe (wife of Ivan III of Russia). [SEP] Knowledge 2: Thomas Palaiologos
Thomas Palaiologos or Palaeologus (1409 – 12 May 1465) was Despot in Morea from 1428 until the Ottoman conquest in 1460, though he continued to claim the title until his death in 1465.Thomas was the younger brother of the final Byzantine emperors John VIII and Constantine XI and also laid claim to the position of emperor following the Fall of Constantinople in 1453, during which Constantine died.From 1453 to 1460, Thomas warred against his brother Demetrios over control of the Morea and over who was the rightful holder of the imperial title.This dispute came to an end when the Ottoman sultan Mehmed II, who had conquered Constantinople seven years prior, invaded the Morea.Thomas fled with his family to Italy and lived in exile in Rome from 1461.In Rome, Pope Pius II recognised him as the rightful "Emperor of Constantinople".Thomas died in 1465 and despite his attempts and hopes, he had failed to garner enough support to kick-start a crusade that could have helped him claim Constantinople and restore the Byzantine Empire.His claims to the position of emperor and Despot of the Morea were maintained after his death by his oldest son Andreas.
