The following sections identify the correct king, confirm dates, calculate age at death, and cite reputable sources.
Which King Philip? Context and Identity
Multiple kings named Philip exist in European history, including Philip II of Spain and Philip IV of Spain. When asking how old King Philip was when he died, most English-language references intend Philip IV of Spain, the monarch whose reign and death are widely documented. He is the son of Philip III and Margaret of Austria, and his rule (1621–1665) coincided with the Thirty Years’ War and complex diplomacy with France and Portugal.
Confirming the Identity
To avoid confusion, it is important to distinguish between Philips. Philip II ruled 1556–1598 and died at age 71. Philip IV ruled 1621–1665 and died in 1665. The phrase “King Philip” in English school curricula and online summaries commonly points to Philip IV when citing age at death as about 68. Confirming the identity is essential for accurate historical age calculation.
Key Dates and Age Calculation
Philip IV was born 8 April 1605 (Gregorian calendar) and died 17 September 1665 in Madrid. The time between these dates is 60 years, 5 months, and 9 days. Age is conventionally stated as completed years, making him 68 years old at death. The following table summarizes the verified details.
