Leibniz defended the Hapsbourg!
FACTS: Leibniz defended the House of Hapsburg during the "War of the Spanish Succession"
Charles II, the product of generations of inbreeding, was unable to rule and remained childless. The line of Spanish Habsburgs came to an end at his death. Charles VI (r. 1711-40) was the last Holy Roman emperor of the direct Hapsburg line. In 1700 he was designated successor in Spain to King Charles II. On his deathbed, however, Charles II left his throne to his nephew, Philip of Anjou (Philip V), grandson of King Louis XIV of France, in the face of counterclaims by Archduke Charles of Austria, who was supported by England and the Netherlands, was the proximate cause of the "War of the Spanish Succession" (1702-14), the first "world war" fought by European powers. Philip was proclaimed king in 1700.
Worth reading is this larouchian internal row on this question, in Spains Carlos III and The American System by William F. Wertz, Jr. and Cruz del Carmen Moreno de Cota:
"Ironically, although Quijano (a former larouchie, note) attempted to twist Leibnizs 1703 attack on Spains Bourbon succession into a defense of the Hapsburgs against the Bourbon kings, Leibnizs actual policies for the promotion of the arts and sciences, and for the development of physical economy for the General Welfare, were implemented by none other than the Bourbon Carlos III."
Bourbon Charles "Carlos" III of Spain (r. 1759-88) was Spain's enlightened despot par excellence. He was one of Europe's most active patrons of the Enlightenment. The principles of the Enlightenment which had come from Prance, tended to allow religious toleration, freedom of speech and the press, and the right to hold private property. Most fostered the arts, sciences, and education (not from Leibniz! Who is twisting History?). Charles "Carlos" III shared these ideals with other enlightened monarchs of the 18th century, including Maria Theresa of Austria, her son Joseph, and Catherine II of Russia (the Great).
