John II (Spanish: Juan; 6 March 1405 – 20 July 1454) was King of Castile and León from 1406 to 1454.
John was the son of King Henry III and his wife, Catherine of Lancaster. His mother was the granddaughter of King Peter, who was ousted by Henry III's grandfather, King Henry II. John succeeded his father on 25 December 1406, and united in his person the claims of both Peter and Henry II. His mother and his uncle, King Ferdinand I of Aragon, were co-regents during his minority. When Ferdinand died in 1416, his mother governed alone until her death in 1418.
John II's reign, lasting 49 years, was one of the longest in Castilian history, but John himself was not a particularly capable monarch. He spent his time verse-making, hunting, and holding tournaments. His favourite, Álvaro de Luna, heavily influenced him until his second wife, Isabella of Portugal, obtained control of his feeble will. At her instigation, he dismissed his faithful and able servant, an act which is said to have caused him much remorse.

John II (Catalan: Joan II), called the Great (el Gran) or the Faithless (el Sense Fe) (29 June 1398 – 20 January 1479), was the King of Navarre through his wife (jure uxoris) from 1425 and the King of Aragon in his own right from 1458 until his death. He was the son of Ferdinand I and his wife Eleanor of Alburquerque.
John was born at Medina del Campo. In his youth he was one of the infantes (princes) of Aragon who took part in the dissensions of Castile during the minority and reign of John II. Till middle life he was also lieutenant-general in Aragon for his brother and predecessor Alfonso V, whose reign was mainly spent in Italy. In his old age he was engaged in incessant conflicts with his Aragonese and Catalan subjects, with Louis XI of France, and in preparing the way for the marriage of his son Ferdinand with Isabella I of Castile which brought about the union of the crowns of Aragon and Castile and which was to create the Kingdom of Spain. His troubles with his subjects were closely connected with tragic dissensions within his own family.
John II (26 April 1319 – 8 April 1364), or Jean II, also called John the Good (French: Jean le Bon), was a monarch of the House of Valois who ruled as King of France from 1350 until his death.
When John II came to power, France was facing several disasters: the Black Death, which caused the death of nearly half of its population; popular revolts known as Jacqueries; free companies of routiers who plundered the country; and English aggression that resulted in disastrous military losses, including the Battle of Poitiers of 1356, in which John was captured.
While John was a prisoner in London, his son Charles became regent and faced several rebellions, which he overcame. To liberate his father, he concluded the Treaty of Brétigny (1360), by which France lost many territories and paid an enormous ransom.
In an exchange of hostages, including his son Louis, John was released from captivity to raise funds for his ransom. Upon his return in France, he created the franc to stabilize the currency and tried to get rid of the free companies by sending them to a crusade, but Pope Innocent VI died shortly before their meeting in Avignon. When John was informed that Louis had escaped from captivity, he voluntarily returned to England, where he died in 1364. He was succeeded by his son Charles V.
