Princess Marie-Cécile of Prussia

Princess Marie-Cécile of Prussia, known after her marriage as Marie-Cécile, Duchess of Oldenburg, was a German member of the House of Hohenzollern, a great-granddaughter of Wilhelm II, the last German Emperor, and a quiet champion of music and of disadvantaged children. She was born Marie-Cécile Kira Viktoria Luise on 28 May 1942 at Cadinen, the imperial family estate in East Prussia (today Kadyny in Poland). She was the eldest daughter and third of the seven children of Louis Ferdinand, Prince of Prussia, and his wife Grand Duchess Kira Kirillovna of Russia.

Her family tree joined two fallen empires. Her paternal grandparents were Wilhelm, German Crown Prince, and Duchess Cecilie of Mecklenburg-Schwerin. Her maternal grandparents were Grand Duke Kirill Vladimirovich of Russia and Princess Victoria Melita of Saxe-Coburg and Gotha, a granddaughter of Queen Victoria, which made Marie-Cécile a distant relative of the British royal family as well.

Her earliest memories were shaped by the end of the Second World War. On 25 January 1945, only hours before Soviet troops reached Cadinen, her father led the family away by horse-drawn sleigh across the frozen Vistula Lagoon (the Frisches Haff). The flight ended the family's life in East Prussia. After a period in Bad Kissingen the family settled in Bremen in 1947 and in 1950 moved to the Wümmehof estate, which became their long-term home. Her father became head of the House of Hohenzollern in 1951 and devoted much of his energy to the family's remaining properties and to restoring Hohenzollern Castle. In 1952 her parents founded the Princess Kira of Prussia Foundation, which brought children from difficult circumstances in post-war Germany, starting with youngsters from Berlin in 1954, for holidays at the castle.

On 3 December 1965 Marie-Cécile married Duke Friedrich August of Oldenburg in a civil ceremony in Berlin, followed the next day by a church wedding at the Kaiser Wilhelm Memorial Church, held according to the traditional Prussian liturgy at her father's request. It was the first Hohenzollern wedding in Berlin since 1913. Thousands of people lined the streets, the regional broadcaster's Berliner Abendschau filmed the day, British Movietone and AP newsreels carried the pictures abroad, and Bunte put the bride on its cover. Willy Brandt, then Governing Mayor of Berlin, attended the reception at Charlottenburg Palace. After the wedding the couple moved to Freetown, Sierra Leone, where Friedrich August worked as an agricultural expert and development consultant.

The couple had three children: Paul-Wladimir (born 1969), Rixa (born 1970) and Bibiane (born 1974). The marriage ended in divorce in 1989. Friedrich August died in 2017.

For most of her adult life Marie-Cécile lived in the Ostholstein district of Schleswig-Holstein in northern Germany, which became her home. She stayed close to the causes her parents had begun, supporting the Princess Kira of Prussia Foundation for decades. Music was her particular passion. She was a founding member and later a deputy chairwoman of the Lübeck branch of Yehudi Menuhin Live Music Now, the charity created by the violinist Yehudi Menuhin to bring live classical music to people who rarely hear it and to give young musicians a stage. Through the Lübeck association she helped arrange concerts in schools, hospitals, care homes, hospices and workshops for people with disabilities across the region. She also kept up her interest in Hohenzollern family history, appearing at readings and historical commemorations.

Marie-Cécile died on 31 October 2026 at the age of 84. The House of Hohenzollern announced her death on Instagram, recalling her birth at Cadinen, her work for children through the family foundation and her special devotion to music and to bringing it to others. The cause and place of her death were not made public. She is remembered as a link to the vanished imperial world of her ancestors who chose to spend her own life on quieter, practical good: holidays for children who needed them and music for people who could not go to the concert hall.
