Queen Elizabeth of Greece (born in October 12, 1894, Sinaia — deceased in November 15, 1956, Cannes) born into the Royal family of Romania (with the titles of Princess of Romania and Princess of Hohenzollern-Sigmaringen) was the eldest daughter of Queen Mary and King Ferdinand.

Before she turned two months, the little princess was baptised Elizabeth, named after her aunt Carmen Sylva, the wife of Charles I. Elizabeth spent the first years of her life especially at Sinaia, where the royal family resided.

Princess Elizabeth was the only child of the six children of King Ferdinand and Queen Mary who did not attend any formal school, but studied in private till the age of 25.

The ending of 1914 changed the life of the Princess. The death of King Charles I and the accession to the throne of her father, Ferdinand I, made the whole family to change its residence in Bucharest, at Cotroceni Palace. The official commitments (obligations) multiplied, the young Elizabeth had to appear with her family at various events and to engage herself in the activity of charity. The Princess was found of the life in capital, preferring to spend as much time in Bucharest.

The peaceful teen age of Elizabeth ends in the summer of 1916 when Romania enters the World War I. At the end of the same year, the royal family together with the government is forced to fall back to/takes refuge in Iași, while Bucharest falls under the occupation of the Germans. During the two years of refuge in Moldavia, Elisabeth lives in a villa at Bicaz, next to Queen Mary and her smaller sisters, Mărioara and Ileana, helping her mother in the nursing work.

On February 27, 1921, in the church upon the hill of the Metropolitan Church from Bucharest, the religious ceremony of Princess Elisabeth of Romania and the heir Prince George of Greece is being officiated, involving several members of the royal families of Europe, and on the 7th of March, they leave the country, heading for their new home. In the spring of 1921, when Elizabeth, as the wife of the heir Prince set her foot for the first time on the territory of Greece, the Greek Royal family status was not one to be envied. With just a few months ago, King Konstantin got back his throne, returning to the country after several years of exile. The population of Greece was further divided into two camps, one revolutionary and the other monarchist, with many tensions between them.

On January 1922, Princess Elizabeth with her husband returns for the first time in Romania since their marriage. In the spring of the same year, she seriously falls ill from typhoid fever. She suffers many surgeries, Queen Mary coming twice to Athens to take care of the sick. A long period of suffering marks the young Princess, she gradually gets isolated from the people around her. At the end of the summer, Elizabeth, weakened by illness, returnes to her native country to attend her parents' coronation as Kings of the Great Romania. During her stay in the Romanian Kingdom, the situation in Greece gets tensed, King Constantine being forced in September 1922 to leave the country again, to abdicate in favor of his son, who swears the oath as George II. On the 20th of October 1922, Elisabeth returnes to Greece as a Queen.

In 1924, after 15 months of his coronation, King George II is forced to abdicate (he will return to the throne once again in 1935) and Elizabeth will renounce to the Crown of Greece with a sense of relief.

First, the couple lives in exile in Bucharest and then in London. The relations between the two of them rapidly get cold, they begin to live separated. They officially get divorced only in 1935, the former Queen Elizabeth becomes Princess again. After returning home, the Princess sets herself down, for several years, at Peleş, avoiding Cotroceni and the capital.

After a few years after the accession to the throne of Romania in 1930, her big brother, the controversial King Carol II, makes a surprising gesture, which proved that he fostered a sense of a particular affection towards his capricious sister. The King ordered the construction of a small and coquettish palace on the bank of Herăstrău Lake, from the revenues of the Royal Crown, which he gives to the Princess. Disturbed by the presence of Elena Lupescu in the Royal Court and not wanting to upset her brother on this theme, she gathers money from the annuity and buys the former mansion of a Hungarian earl in Banat, in the locality of Banloc. She permanently retires there, followed by two maids that remained faithful to her till the end.

The seizure of power by the Communists after the end of World War II, these being against the monarchy and they wanted the country to turn into a Republic, complicated the situation of the members of the royal family. King Mihai I is forced to abdicate on the 30th of December 1947, all members of the family being compeled to leave the country as soon as possible. On the 4th of January 1948, the Royal train which included King Mihai, Queen Mother Elena and Princess Ileana stopped in Banloc station. On the platform planks, there were three women: the former Queen of Greece, Princess Elizabeth, along with two maids, each one with a hand suitcase. After their boarding, the train set out on its way to exile, there was to be no return for Elisabeth.

After spending a short period in the castle of her German relatives at Sigmaringen, the Princess settled in Cannes on the Côte d'Azur, where she rented an apartment. Later she began to give piano lessons. Princess Elizabeth died on the 15th of November 1956, at the age of 62, and she was buried on the French Riviera.
