Philip was born in 1292, the second son of King Philip IV of France and Joan I of Navarre, and he was granted the County of Poitiers while his brother Louis X of France inherited the throne in 1314. Philip claimed the regency for Louis' son Jean I of France when he became king on his birth in 1316, and he would succeed him when he died prematurely. His niece Joan II of Navarre sought to challenge his legitimacy to gain power for herself, but Philip pointed out that her mother Margaret of Burgundy was involved in the "Tour de Nesle Affair", in which Princess Isabella of France claimed that several of Philip IV's daughters-in-law were adulterers. The Estates General concluded that all women would be excluded from the line of succession, establishing Salic law; Philip V set a precedent for several more centuries of French rulers. Philip restored good relations with the County of Flanders during his rule, but he grew angry at King Edward II of England when he refused to pay homage to him, and the Shepherds' Crusade of 1320 turned into a popular crusade to Iberia from Normandy into a series of attacks on castles, royal officials, priests, lepers, and Jews in southern France. Philip died of dysentery in 1322, and his younger brother succeeded him as Charles IV of France.
