In 1700, at the death of Charles II of Spain, the Spanish Habsburgs became extinct in the male line. Under the will of the childless Charles II, the second grandson of Louis XIV of France was named as his successor, to the union of the thrones of France and Spain. The prince, then Duke of Anjou, became Philip V of Spain. Permanent separation of the French and Spanish thrones was secured when France and Spain ratified Philip's renunciation, for himself and his descendants, of the French throne in the Treaty of Utrecht in 1714, and similar arrangements later kept the Spanish throne separate from those of the Two Sicilies and Parma. The Spanish House of Bourbon (rendered in Spanish as "Borbón" ) has been overthrown and restored several times, reigning 1700–1808, 1813–1868, 1875–1931, and since 1975. Bourbons ruled in Naples from 1734 to 1806 and in Sicily from 1734 to 1816, and in a unified Kingdom of the Two Sicilies from 1816 to 1860. They also ruled in Parma from 1731 to 1735, 1748–1802 and 1847–1859.
