text: When Antonio I of Monaco and his wife Marie de Lorraine-Armagnac were looking for a consort for their daughter and heir Louise Hippolyte of Monaco, the family proposed him as a candidate. His candidacy was supported by King Louis XIV of France, who wanted to solidify French influence in Monaco.
  Jacques and Louise Hippolyte married on 20 October 1715 and had nine children. The wedding ceremony was the first official act that the five-year-old king, Louis XV, carried out during the Regency of Philippe II, Duke of Orléans.
  The marriage wasn't very happy. Jacques preferred to stay more in Versailles, where he had several mistresses, than in Monaco.
  After the death of Antonio I of Monaco, Louise Hippolyte traveled from Paris to Monaco on 4 April 1731 and received an enthusiastic  reception by the population. When Jacques joined her several times later, the reception was much colder.
  Jacques served as regent for his wife from 21 February 1731 to her death. At the end of 1731, Louise Hippolyte died of smallpox. Jacques I neglected the affairs of state and, under pressure from the population, had to leave the country in May 1732.
  Jacques abdicated in favor of his son Honoré on November 7, 1733.
