Editing Charles V of France (section)

===First Dauphin of the French Royal House===
[[Humbert II of Viennois|Humbert II, Dauphin of Viennois]], ruined due to his inability to raise taxes after a crusade in the Middle East, and childless after the death of his only son, decided to sell the Dauphiné, which was a fief of the [[Holy Roman Empire]]. Neither the pope nor the emperor wanted to buy and the transaction was concluded with Charles' grandfather, the reigning King [[Philip VI of France|Philip VI]].

Under the [[Treaty of Romans]], the Dauphiné of Viennois was to be held by a son of the future king [[John II of France|John the Good]]. So it was Charles, the eldest son of the latter, who became the first Dauphin. At the age of twelve, he was suddenly vested power while in [[Grenoble]] (10 December 1349 to March 1350). A few days after his arrival, the people of Grenoble were invited to the Place Notre-Dame, where a platform was erected. Young Charles took his place next to Bishop John of Chissé and received the oath of allegiance of the people. In exchange, he publicly promised to respect the community charter and confirmed the liberties and franchises of Humbert II, which were summed up in a solemn statute before he signed his abdication and granted a last amnesty to all prisoners, except those facing the penalty of death.

On 8 April 1350 at [[Tain-l'Hermitage]], the Dauphin married his cousin [[Joanna of Bourbon]] at the age of 12. The prior approval of the pope was obtained for this [[Consanguinity|consanguineous]] marriage (both were descended from [[Charles, Count of Valois|Charles of Valois]]). The marriage was delayed by the death of his mother [[Bonne of Luxembourg]] and his grandmother [[Joan the Lame of Burgundy|Joan the Lame]], swept away by the plague (he no longer saw them after he left for the Dauphiné). The dauphin himself had been seriously ill from August to December 1349. Gatherings were limited to slow the spread of the plague then raging in Europe, so the marriage took place in private.

The control of Dauphiné was valuable to the [[Kingdom of France]], because it occupied the [[Rhône]] Valley, a major trade route between the [[Mediterranean Sea|Mediterranean]] and [[northern Europe]] since ancient times, putting them in direct contact with [[Avignon]], a papal territory and diplomatic center of [[Middle Ages|medieval Europe]]. Despite his young age, the dauphin applied to be recognized by his subjects, interceding to stop a war raging between two vassal families, and gaining experience that was very useful to him.
