Philip V of Spain
Philip V (19 December 1683 – 9 July 1746) was King of Spain from 1 November 1700 to his abdication in favour of his son Louis on 14 January 1724, and from his reaccession of the throne upon his son's death, 6 September 1724 to his own death on 9 July 1746.
Before his reign, Philip occupied an exalted place in the royal family of France as a grandson of King Louis XIV.
His father, Louis, Grand Dauphin, had the strongest genealogical claim to the throne of Spain when it became vacant in 1700.
However, since neither the Grand Dauphin nor Philip's older brother, Louis, Duke of Burgundy, could be displaced from their place in the succession to the French throne, the Grand Dauphin's maternal uncle (Philip's granduncle)
King Charles II of Spain named Philip as his heir in his will.
It was well known that the union of France and Spain under one monarch would upset the balance of power in Europe, such that other European powers would take steps to prevent it.
Indeed, Philip's accession in Spain provoked the 13-year War of the Spanish Succession, which continued until the Treaty of Utrecht forbade any future possibility of unifying the French and Spanish crowns while confirming his accession to the throne of Spain.
Philip was the first member of the French House of Bourbon to rule as King of Spain.
The sum of his two reigns, 45 years and 21 days, is the longest in modern Spanish history.
