in 1498, when the duchy of Orleans was united with the royal domain. In 1626 Louis XIII. created his brother, Jean Baptiste Gaston (d. 166o), duke of Orleans, and the title was revived in 1661 by Louis XIV. in favour of his brother Philip. Descendants of this duke have retained the title until the present day, one of them becoming king of France as Louis Philippe in 183o. Two distinguished families are descended from the first house of Orleans: the counts of Angouleme, who were descended from John, a son of Duke Louis I., and who furnished France with a king in the person of Francis I. ; and the counts and dukes of Longueville, whose founder was John, count of Dunois, the bastard of Orleans, a natural son of the same duke. In addition to the dukes of Orleans the most important members of this fam ily are: Anne Marie Louise, duchess of Montpensier ; Francis, prince of Joinville ; Louis Philippe Albert, count of Paris; and the traveller Prince Henry of Orleans.
