John I, called the Posthumous, was King of France and Navarre, as the posthumous son and successor of Louis X, for the four days he lived in 1316. He is the youngest person to be king of France, the only one to have borne that title from birth, and the only one to hold the title for his entire life. His reign is the shortest of any undisputed French king. Although considered a king today, his status was not recognized until chroniclers and historians in later centuries began numbering John II, thereby acknowledging John I's brief reign.

Louis X, known as the Quarrelsome, was King of France from 1314 and King of Navarre as Louis I from 1305 until his death. He emancipated serfs who could buy their freedom and readmitted Jews into the kingdom. His short reign in France was marked by tensions with the nobility, due to fiscal and centralisation reforms initiated during the reign of his father by Grand Chamberlain Enguerrand de Marigny.
