While on work assignment in
Rio de Janeiro in September 1988, Marie attended a dinner hosted by
Princess Isabel of Brazil (born 1944), where she met their mutual cousin
Prince Gundakar of Liechtenstein Her grandfather reportedly called the decision "treason", as tradition dictated that a French
princess of the Blood Royal weds in France unless the groom is the ruler or
heir apparent of a foreign realm. The conflict was aggravated by divided family loyalties: instead of
Dreux, the wedding was to be held at
Friedrichshafen Castle in Germany, childhood home of the bride's mother. Princess Marie spent much time there in her youth during visits to her maternal grandparents. However, because her mother's brother
Carl, Duke of Wurttemberg, now lived there with his wife
Diane d'Orléans, sister of the Count of Clermont and daughter of the Count of Paris, relatives and members of foreign royal dynasties found themselves being urged by two sets of siblings, long married to each other, to take opposite sides in the families' quarrel. Marie declared, "It's in that castle that I've been happiest. It's there and only there that I will be married". The compromise she announced, to hold the mandatory
civil wedding at Dreux and to follow with Catholic nuptials at Friedrichshafen, failed to appease the head of the Orléans family;
Monseigneur refused to attend either ceremony, as did Clermont. Nonetheless, that was the arrangement which transpired. Marie wed her prince civilly at Dreux's city hall on 22 July 1989, and religiously in the castle church of Friedrichshafen, on 29 July 1989. Only eight persons, including bride and groom, attended the civil wedding in France (including the Duchess of Montpensier, her son
Prince Jean, Duke of Vendôme, and a brother of the groom). Although 250 guests attended the ceremony in Germany, absent were the Count of Clermont, the Count of Paris and all but two of Clermont's eight siblings; the hostess Diane, Duchess of Wurttemberg, was present, as was her brother Prince Jacques, Duke of Orléans, and their mother,
Madame the Countess of Paris. This was the first marriage of a member of the House of Orléans into a
reigning dynasty since the 1929 wedding of
Princess Françoise of Orléans to
Prince Christopher of Greece. Gundakar is a third cousin of his sovereign,
Hans Adam II of Liechtenstein, and is in the
line of succession to that principality's throne. Gundakar Albert Alfred Petrus of Liechtenstein is the eldest son of Prince Johann of Liechtenstein and Princess Clothilde of
Thurn und Taxis. He has a twin sister, Princess Diemut, and five younger siblings. ==Children==
