General Notes

John II (of Aragón and Navarre), in Spanish, Juan II (1397-1479), king of
Aragón (1458-1479) and Navarre (1425-1479), the son of King Ferdinand I of
Aragón and father of King Ferdinand V. John represented his brother King
Alfonso V of Aragón, Naples, and Sicily in Aragón as lieutenant general and
succeeded him to the throne of Aragón. In 1420 John married Blanche of
Navarre, who inherited the throne of Navarre in 1425. For many years, John
struggled with his son, Charles, later King Charles IV of Navarre for control
of the two kingdoms. After Charles's death in 1461, John was faced with a
series of revolts in the province of Catalonia led by Charles's former
supporters. He did not regain control of the province until 1472. During the
latter part of his reign, John engaged in war against King Louis XI of France
and was forced to cede to him the provinces of Cerdagne and Roussillon.
