Note X — Chapter XI · Intrigues and Wars.
Reading edition
The claim of the young prince was founded upon the fact that his grandmother, Maria Theresa, was the eldest daughter of Philip IV. of Spain. She had, however, upon her marriage, renounced all claim to the succession. Her younger sister, Margarita, had married the Emperor Leopold of Austria without this renunciation. The emperor claimed the crown for her daughter, who had married the Elector of Bavaria. Hence the war of The Spanish Succession.
