The Kingdom of Romania was a constitutional monarchy in Central-Eastern Europe, ruled by a royal family that was a branch of the Hohenzollern dynasty. The kingdom existed from 1881, when Carol I of Romania was proclaimed king, until 1947, when the last king, Michael I of Romania, abdicated and the Parliament proclaimed Romania a republic. Soon after, upon the establishment of the constitution of 13 April 1948, Romania became a popular republic, a regime that lasted until 1989. Members of the former royal family include the daughters of the late, former King Michael of Romania. Some descendants have adopted the surname "of Romania". There are also descendants of Michael's older half-brother Carol Lambrino, whose legitimacy was disputed and who were not recognised as royal during the reigns of Ferdinand, Carol II and Michael. King Michael publicly renounced for himself, the former queen, and their five daughters any claim to the titles of "Prince/Princess of Hohenzollern", styles which were in any case not recognised under German laws since 1919 but had been attributed, along with the Romanian royal titles, to members of the Romanian dynasty in such subsequently-published sources as the Almanach de Gotha and Burke's Guide to the Royal Family.
div. Kazimierz Wiesław Mystkowski Daughters of Romania's kings, such as Margareta, Elena, Irina and Sophie, as well as their descendants, had no rights of succession to the Romanian throne during the monarchy's existence, in accordance with the Salic law enshrined in both the defunct royal Romanian Constitution of 1938 and the Statute of the Romanian royal house, dated 1884. On 30 December 2007 in a private ceremony, King Michael issued a declaration in the form of a statute, an act of symbolic significance in the absence of its approval by the Parliament, promulgating new Fundamental Rules of the Royal Family of Romania. Michael decided to add his daughters and their children to the headship of the royal house, further explicitly banning any other foreigners belonging to any other royal or princely house from succeeding. On the same occasion he asked the Romanian Parliament to abolish the Salic law, should it consider restoring the monarchy. By the same act, Michael designated his grandson Nicholas de Roumanie Medforth-Mills as a future member of the deposed royal family and future "Prince of Romania" with the style of "Royal Highness," effective either on his 25th birthday, 1 April 2010, or upon Michael's death, whichever might occur sooner. On 1 August 2015, however, King Michael issued a declaration retracting the style "Royal Highness" and "of Romania" previously conferred upon Nicholas, also excluding him from the line of succession to the headship of the dynasty, noting that his successors in that capacity should be persons of "principled modesty and morality." Children and consorts of the members of the family who do not bear a royal title are not recognised as members of the former royal family, according to the new rules.
The titles of the members of the Royal House of Romania, as well as the order of succession are determined by the Organic Norms of the Royal House of Romania. Thus, according to them, the current head of the Royal House of Romania is Crown Princess Margareta. The current consort of the head of the Royal House of Romania is Prince Radu. The current successor to the head of the Royal House of Romania is Princess Elena. The members of the Royal House of Romania are as follows: Margareta, Custodian of the Romanian Crown; Prince Radu; Princess Elena; Princess Sofia. The spouses and children of the princesses do not hold royal titles. The order of succession to the head of the Royal House of Romania is based on the principle of primogeniture with male preference, the Organic Norms thus abrogating the willow principle of absolute male primogeniture, excluding women and their descendants. Basically, at present, this is the following:
