Charles IV of France Birthday, Date of Birth

Charles IV (18/19 June 1294 – 1 February 1328), called the Fair (le Bel) in France and the Bald (el Calvo) in Navarre, was the last king of the direct line of the House of Capet, King of France and King of Navarre (as Charles I) from 1322 to 1328. Charles was the third son of Philip IV; like his father, he was known as "the fair" or "the handsome".

Beginning in 1323 Charles was confronted with a peasant revolt in Flanders, and in 1324 he made an unsuccessful bid to be elected Holy Roman Emperor. As Duke of Guyenne, King Edward II of England was a vassal of Charles, but he was reluctant to pay homage to another king. In retaliation, Charles conquered the Duchy of Guyenne in a conflict known as the War of Saint-Sardos (1324). In a peace agreement, Edward II accepted to swear allegiance to Charles and to pay a fine. In exchange, Guyenne was returned to Edward but with a much-reduced territory.

When Charles IV died without a male heir, the senior line of the House of Capet, descended from Philip IV, became extinct. He was succeeded in Navarre by his niece Joan II and in France by his paternal first cousin Philip of Valois. However, the dispute on the succession to the French throne between the Valois monarchs descended in male line from Charles's grandfather Philip III of France, and the English monarchs descended from Charles's sister Isabella, was a factor of the Hundred Years' War.
