text: A prince noted for the permissiveness of his private life, Louis I's prodigality was notorious. While visiting England in 1677 he incurred the ire of King Charles II by showering expensive gifts on Hortense Mancini, the king's mistress. The English and Prince Louis later became political enemies when Louis took part in the Anglo-Dutch Wars against England, leading his own Monaco Cavalry into battles in Flanders and Franche-Comté. These acts earned Louis the gratitude of Louis XIV who made him ambassador to the Holy See, charged with securing the Spanish Succession. However, the cost of upholding his position at the papal court caused him to sell most of his grandfather Honoré II's art collection, denuding the palace he had earlier so spectacularly enhanced. Louis died before securing the Spanish throne for France, an act which would have earned the Grimaldi huge rewards. Instead Europe was immediately plunged into turmoil as the War of the Spanish Succession began.
  In 1701, Prince Antoine succeeded Louis I and inherited an almost bankrupt Monaco, though he did further embellish the Royal Room. On its ceiling, Gregorio de Ferrari and Alexandre Haffner depicted a figure of Fame surrounded by lunettes illustrating the four seasons.
  Antoine's marriage to Marie of Lorraine was unhappy and yielded only two daughters. Monaco's constitution confined the throne to members of the Grimaldi family alone, and Antoine was thus keen for his daughter Princess Louise-Hippolyte (Illustration 11) to wed a Grimaldi cousin. However, the state of the Grimaldi fortunes, and the lack of (the politically necessary) approval from King Louis XIV, dictated otherwise. Louise-Hippolyte was married to Jacques de Goyon Matignon, a wealthy aristocrat from Normandy. Louise-Hippolyte succeeded her father as sovereign of Monaco in 1731 but died just months later. The King of France, confirming Monaco's subservient state to France, ignored the protests of other branches of the Grimaldi family, overthrew the Monégasque constitution, and approved the succession of Jacques de Goyon Matignon as Prince Jacques I.
