Jacques (Jacques Honoré Rainier, born 10 December 2014) is the Hereditary Prince of Monaco, the heir of his father, Prince Albert II [1][2]. He bears the title Marquis des Baux [1][2]. This page uses only the information published by the Prince's Palace and the Journal de Monaco.
Birth
The Prince and Princess of Monaco announced the birth of their twins, which took place on 10 December 2014 at the maternity unit of the Centre Hospitalier Princesse Grace [1]. The announcement stated that Prince Jacques has the status of Hereditary Prince, and that his sister, Princess Gabriella, is second in the line of succession, with the title Countess of Carladès [1].
Marquis des Baux
The Palace announcement links the title to "historical usage established by the Treaty of Péronne (1641)" [1]. The next day, Sovereign Ordinance No. 5.105 of 11 December 2014, published in the Journal de Monaco, provided that the Hereditary Prince, "Our beloved son", would bear the title of Marquis des Baux "according to historical usage", and repealed Ordinance No. 1.739 of 16 March 1958, cited in its preamble [2].
