The Kingdom of Romania (Romanian: Regatul României) was a constitutional monarchy in Southeastern Europe, ruled by a royal family that was a branch of the Hohenzollern-Sigmaringen dynasty. The Kingdom existed from 1881, when prince 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, after the establishment of the constitution of 13 April 1948, Romania became a socialist 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 (also known as "Carol Hohenzollern" and "Carol Mircea Grigore of Romania" or, in Romanian, al României, on his amended, Romanian birth certificate)), whose legitimacy was disputed and who were not recognised as royals 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.

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.
