At the time Portugal presented a strange spectacle to the rest of Europe. D. Afonso VI, son of the fortunate D. João de Bragança, was in possession of the throne and was an insane imbecile. His wife, daughter of the Duke of Nemours and cousin of Louis XIV, dared hatch a plot to oust her husband from the throne. The king's stupidity justified the queen's bravado. Despite being master of unusual strength and having slept with his wife for a long time, she accused him of being impotent.
