King of France (1316).
John I was the posthumous son of Louis X the Stubborn, who died leaving his wife Clemenza of Hungary pregnant. John was the long-awaited heir but he lived only a few days and may have been murdered at his uncle's instigation. For the fust time since 987 A.D and the accession of the Capetian dynasty, there was no direct male descendent. The Crown therefore passed to Philip V the Long, second son of Philip the Fair.
