Margareta of Romania

Margareta of Romania, self-styled as Custodian of the Romanian Crown, (Romanian: Custode al Coroanei române; born 26 March 1949) is the eldest daughter of King Michael I and Queen Anne of Romania. She assumed her father's duties in March 2016, upon his retirement, and has claimed the headship of the House of Romania since his death on 5 December 2017. She also heads the Margareta of Romania Royal Foundation.

Until 2011, Margareta also used the style of a princess of Hohenzollern. Margareta has four sisters and no brothers or children. Her heir presumptive is her next sister, Princess Elena of Romania.

Under the defunct royal constitutions of 1923 and 1938 which followed agnatic primogeniture, Margareta and her sisters would not have been in the line of succession to the throne. On 30 December 2007, King Michael designated Margareta as heir presumptive to the defunct throne by an act that is not recognized by the Romanian government and lacks legal validity without approval by Romania's Parliament. On the same occasion, Michael also requested that, should the Romanian Parliament consider restoring the monarchy, the Salic law of succession not be reinstated, allowing female succession. According to the new statute of the Romanian Royal House as declared by Michael, no illegitimate descendants or collateral lines may claim dynastic privileges, titles or rank and any such are excluded from the Royal House of Romania and from the line of succession to the throne.
