John, Duke of Touraine
John, Dauphin of France and Duke of Touraine( 31 August 1398 – 5 April 1417) was the fourth son and ninth child of Charles VI of France and Isabeau of Bavaria.
He was born in Paris.
After his three elder brothers died, he became Dauphin in 1415.
In 1406 he married Jacqueline, heiress of the County of Hainaut, Holland, Zealand, and Frisia.
After his marriage to Jacqueline, he was brought up at the castle of Le Quesnoy in Hainaut, at the court of his mother- in- law, Margaret of Burgundy.
This arrangement was made between his father and his father- in- law to ensure his safety away from the tulmultous court in Paris, as well as to acquaint him with the lands which he would rule as husband of Jacqueline after her father's death.
After the death of his elder brother Louis in December 1415, he became the next Dauphin of France.
He died on 5 April 1417 at the age of eighteen.
What exactly caused his death is disputed.
According to some, he died of the consequences of an abscess to the head, while other sources suggest he had been poisoned.
He was buried in Compiègne's Saint- Corneille abbey.
His younger brother Charles became dauphin and eventually king.

Charles Orlando, Dauphin of France

Charles VIII of France
Charles VIII, called the Affable (30 June 1470 – 7 April 1498), was King of France from 1483 to his death in 1498.
He succeeded his father Louis XI at the age of 13.
His elder sister Anne acted as regent jointly with her husband Peter II, Duke of Bourbon until 1491 when the young king turned 21 years of age.
During Anne's regency, the great lords rebelled against royal centralisation efforts in a conflict known as the Mad War (1485–1488), which resulted in a victory for the royal government.
In a remarkable stroke of audacity, Charles married Anne of Brittany in 1491 after she had already been married by proxy to the Habsburg Holy Roman Emperor Maximilian
I in a ceremony of questionable validity.
Preoccupied by the problematic succession in the Kingdom of Hungary, Maximilian failed to press his claim.
Upon his marriage, Charles became administrator of Brittany and established a personal union that enabled France to avoid total encirclement by Habsburg territories.
To secure his rights to the Neapolitan throne that René of Anjou had left to his father, Charles made a series of concessions to neighbouring monarchs and conquered the Italian peninsula without much opposition.
A coalition formed against the French invasion of 1494–98 finally drove out Charles' army, but Italian Wars would dominate Western European politics for over 50 years.
Charles died in 1498 after accidentally striking his head on the lintel of a door at the Château d'Amboise, his place of birth.
Since he had no male heir, he was succeeded by his cousin Louis XII of France from the Orléans cadet branch of the House of Valois.
