The End of John II of Aragon

John II of Aragon lived to the age of 80. He had been married twice, had a few children (one whom he treated poorly, a few who had better careers), including a few illegitimate ones who did all right for themselves (one became a Duke of Villahermosa, one became the Archbishop of Zaragoza).

He caused the Navarrese Civil War (1451-1455) because he refused to allow his son Charles, Prince of Viana, to inherit Navarre. That war could be said to have stretched out with periods of civil unrest until 1461, when Charles died, possibly poisoned by John's second wife.

Because of John's mistreatment of Charles and the Navarre succession, he also had to deal with a Catalan Civil War, also called quite specifically the "War Against John II." Some in the Principality of Catalonia wished to support Charles' rightful claim to Navarre, some were willing to back John's actions. 

After a lot of back-and-forth (the French weighed in on John's side as well), including Catalans bringing in pretenders to the throne to try to push John out, and lawyers enumerating the violations of the constitution of which John was guilty, it all ended when Charles died in 1461. Navarre went to John's daughter Eleanor  for about two weeks in 1479 and then passed to Francis Phoebus, another Prince of Viana.

At the end of John's life he suffered from cataracts and was blind by the age of 70. Fortunately for him, he had a surgeon who restored his eyesight through surgery. That surgeon was a Jew named Abiathar Crescas, who was also a leader among Jews of Aragon. When John died, Abiathar preached a memorial sermon at the funeral service.

Tomorrow we'll look into the medieval surgical technique for cataract removal.
