Philip V of France in the context of "Count of Poitiers"

Joan II (French: Jeanne, Spanish: Juana II, Basque: Joana II; 28 January 1312 – 6 October 1349) was Queen of Navarre from 1328 until her death in 1349.

Joan was the only surviving child of Louis I of Navarre and Margaret of Burgundy. Her father ascended the French throne as Louis X in 1314. Joan's paternity was dubious because her mother was involved in a scandal, but Louis declared her his legitimate daughter before he died in 1316. However, the French lords were opposed to the idea of a female monarch and elected Louis's brother king as Philip V. The Navarrese noblemen also paid homage to Philip. Joan's maternal grandmother, Agnes of France, and uncle, Odo IV of Burgundy, made attempts to secure the counties of Champagne and Brie (which had been the patrimony of Joan's paternal grandmother, Joan I of Navarre) to Joan, but the French royal troops defeated her supporters. After Philip V married his daughter to Odo and granted him two counties as her dowry, Odo renounced Joan's claim to Champagne and Brie in exchange for a compensation in March 1318. At this time, Joan married her cousin Philip of Évreux (later Philip III of Navarre).

In the Middle Ages, a familiaris (plural familiares), more formally a familiaris regis ("familiar of the king") or familiaris curiae ("of the court"), was, in the words of the historian W. L. Warren, "an intimate, a familiar resident or visitor in the [royal] household, a member of the familia, that wider family which embraces servants, confidents, and close associates." Warren adds that the term "defies adequate translation", but is distinct from courtier, "for the king employed his familiares on a variety of administrative tasks."

The familiares of a king are collectively referred to as the familia regis, which evolved into a private royal council—in England during the reign of Henry III (1216–72) and in France during that of Philip V (1316–22). In England, it was known as the concilium familiare or concilium privatum (Privy Council) and in France as the magnum consilium (great council, the Conseil du Roi). The familiares regis may have already formed an inner royal council in Sicily during the reign of Roger II (1130–54).

Louis X (4 October 1289 – 5 June 1316), known as the Quarrelsome (French: le Hutin), 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.

Louis' first wife, Margaret, was implicated in the Tour de Nesle affair. She was found guilty of infidelity and imprisoned until her death in August 1315. Louis married Clémence of Hungary the same year, but the king died in 1316 leaving his wife pregnant. Queen Clémence gave birth to a boy, who was proclaimed king as John I, but the infant lived only five days. Louis' brother Philip, Count of Poitiers, succeeded John to become Philip V of France.

John I (15 November 1316 – 19 November 1316), called the Posthumous (French: Jean I le Posthume, Occitan: Joan I lo Postume), was the 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 been king 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 as 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.

John reigned for four days under the regency of his uncle, Philip V of France, until his death on 19 November 1316. His death ended the three centuries of father-to-son succession to the French throne. The infant king was buried in the Basilica of Saint-Denis. He was succeeded by his uncle, Philip, whose contested legitimacy led to the re-affirmation of the Salic law, which excluded women from the line of succession to the French throne.
