Philip was born in Lyon, the second son of King Philip IV of France and Queen Joan I of Navarre. His father granted to him the county of Poitiers in appanage. Modern historians have described Philip V as a man of "considerable intelligence and sensitivity", and the "wisest and politically most apt" of Philip IV's three sons. Philip was influenced by the troubles and unrest that his father had encountered during 1314, as well as by the difficulties his older brother, Louis X, known as "the Quarreler", had faced during the intervening few years. At the heart of the problems for both Philip IV and Louis X were taxes and the difficulty in raising them outside of crises.
