Nicholas Michael de Roumanie Medforth-Mills, formerly Prince Nicholas of Romania (born 1 April 1985), is the eldest child and only son of Princess Elena of Romania and Robin Medforth-Mills. As a grandson of the former king of Romania, Michael I, he was third in line to the defunct throne of Romania according to a new family statute enacted in 2007,which was abrogated in 2015.

In 1997, Romanian monarchists intended to ask Michael to designate a male heir-presumptive from the House of Hohenzollern, in keeping with the rules of the last royal constitution which were based on agnatic primogeniture and “Salic law”; The monarchists eventually agreed on a compromise and requested him to designate a male rather than female heir-presumptive, in the person of Nicholas. However, under the influence of Queen Anne, Michael rejected the monarchists’ request and at the end of 1997, he designated Princess Margareta, as heir presumptive in keeping with the European Convention on Human Rights, which meant Nicholas would only succeed to the headship of the royal family after the deaths of King Michael, Crown Princess Margareta and his mother.

In 2005, Michael told Nicholas that should he want, he could choose to have the chance of becoming a “Prince of Romania” which would mean assuming responsibility in a conscious manner by starting to work for the country. Gradually after many talks and deep consideration Nicholas decided that he would devote his life to Romania.

On 30 December 2007 the press office of King Michael announced that Nicholas would receive the title “Prince of Romania” with the style of “Royal Highness”, coming into effect on Nicholas’s 25th birthday. On 1 April 2010,by virtue of his new title, he became a member of the Romanian royal family and was also decorated with the Nihil Sine Deo, the highest of royal decorations at the time.

In February 2008, Nicholas stated in an interview with the Romanian daily newspaper Cotidianul that if the Romanian people asked him to become king, he would not refuse.

In September 2012, after his gap year and university studies, he moved to Romania to undertake more of the royal family’s public activities.

On 1 August 2015, former King Michael of Romania signed a document removing the title Prince of Romania and the qualification of Royal Highness from his grandson, Nicholas. Nicholas has also been removed from the line of succession. The former king took the decision that the royal family on the consideration that Romania needed a ruling marked by modesty and moral principles, respect and always thinking of others after the “reign and life” of his eldest daughter, Crown Princess Margarita. The former king hopes that “Nicholas will find in future years a suitable way to serve the ideals and use the qualities that God gave him”. Nicholas’s mother, Princess Elena, received notification of the former king’s decision in a personal letter.
