George, Duke of Mecklenburg

George, Duke of Mecklenburg (German: Georg Herzog zu Mecklenburg; 5 October [O.S. 22 September] 1899 – 6 July 1963) was the head of the House of Mecklenburg-Strelitz from 1934 until his death. Through his father, he was a direct descendant (great-great-grandson) of Russian Emperor Paul I.

He was born in Oranienbaum, Russia as Count George of Carlow; he was the youngest child and only son of Duke George Alexander of Mecklenburg (6 June 1859 - Saint Petersburg, 5 December 1909) and his morganatic wife (m. Remplin, 6 June 1889) Nataliya Fyodorovna Vonlar-Larskaya, Countess of Carlow (Saint Petersburg, 16 May 1858 - Cannes, 14 March 1921), daughter of Fyodor Ardalionovich Vonlar-Larsky (Dagoutze Chavli, Georgia, 23 December 1835 - 2 February 1903) and wife Mariya Fyodorovna Uvarova, and granddaughter of Ardalion Alexeievich Vonlar-Larsky, born in Poretchie, near Smolensk, and wife Tatyana, daughter of Mariya Mikhailovna Litvinova. Because his parents marriage was morganatic, at birth he was denied the title Duke of Mecklenburg; instead his title came from his mother, who had been created Countess of Carlow on 18 March 1890 by her husband's uncle Grand Duke Friedrich Wilhelm of Mecklenburg-Strelitz. When his father died in 1909, his uncle Duke Charles Michael was appointed guardian of George and his sisters Katharina, Marie and Natalia by Grand Duke Adolf Friedrich V of Mecklenburg-Strelitz. After the 1917 October Revolution George and his family fled Russia heading first to France before later moving to Germany.

On 11 September 1928 George was adopted by his uncle Duke Charles Michael, who was the head of the House of Mecklenburg-Strelitz. The adoption was confirmed in the courts in Malchin on 5 October 1928 and as a result he took his uncle and adopted father's surname of Mecklenburg. Following his adoption, George assumed the title Duke of Mecklenburg with the style Serene Highness. This was confirmed by the head of the Imperial House of Russia, Grand Duke Cyril Vladimirovich on 18 July 1929 and recognised on 23 December by Grand Duke Friedrich Franz IV of Mecklenburg-Schwerin. Duke George studied political science at the University of Freiburg and became a Doctor of Economics and Social Sciences.

On 6 December 1934, his uncle Duke Charles Michael died, and George succeeded him as head of the House of Mecklenburg-Strelitz. He lived with his family at Schloss Remplin until April 1940, when the main part of the palace was burnt down. The Grand Ducal family then moved to Grunewald, where they lived until their home was destroyed in an Allied bombing raid in February 1944. In August 1944, George was arrested by the Gestapo and sent to Sachsenhausen concentration camp by the Nazi government, where he remained until February 1945. Following his release, Duke George and his family moved to Sigmaringen at the invitation of Princess Margarete of Hohenzollern (wife of Frederick, Prince of Hohenzollern) in March 1945.

On 18 December 1950 the House of Mecklenburg-Schwerin confirmed the decisions made in 1929 regarding George's title, and he assumed the style of Highness while his status as head of the House of Mecklenburg-Strelitz was also confirmed. At the same time, the Count of Carlow title was abolished.

George died in Sigmaringen, Germany of a heart attack. He was succeeded as head of the Grand Ducal House by his eldest son Duke Georg Alexander.

Duke George was married firstly in Geneva, Switzerland on 7 October 1920 to Irina Mikhailovna Raievskya, Countess Tolstoy (Tsarskoye Selo, 18 August 1892 - Sigmaringen, 22 January 1955) the widow of Count Alexander Mikhailovich Tolstoy (Saint Petersburg, 17 January 1888 - Mishkor, Crimea, 19 February 1918), daughter of Mikhail Nikolaievich Rayevsky (1841–1893) and Princess Mariya Grigoryevna Gagarina (Tiflis, 14 June 1851 - Cannes, 2 August 1941) and granddaughter of Nikolai Nikolaievich Rayevsky (14 September 1801 - 1843) and wife (m. 22 January 1839) Anya Mikhailovna Borozdine, and Prince Grigory Grigoryevich Gagarin and wife Sofiya Andreievna Dashkova. Irina was daughter of the Rayevski family who were one of heirs of the famed Grigori Potemkin, Prince of Tauria, descending from the childless Prince's sister. The couple had four children though one son Alexander born on 3 August 1922 died at the age of just eighteen days. The children who survived into adulthood were.
