Olga Nikolaevna of Russia (11 September 1822 – 30 October 1892) was a member of the Russian imperial family who by marriage to Charles I of Württemberg became Queen consort of the Kingdom of Württemberg until Charles' death. She was the second daughter of Nicholas I of Russia and Charlotte of Prussia. She was thus a sister of Alexander II of Russia. She married King Charles of Württemberg, with whom she had no children. Early life Grand Duchess Olga of Russia was born on 11 September 1822 in St. Petersburg, Russia. Her father was Emperor Nicholas I of Russia, the son of Emperor Paul I of Russia and Empress Maria Feodorovna of Russia (née Duchess Sophia Dorothea of Württemberg). Her mother was Empress Alexandra of Russia (née Princess Charlotte of Prussia), the daughter of King Frederick William III of Prussia and Queen Louise of Prussia (née Duchess Louise of Mecklenburg-Strelitz). Olga grew up as part of a close family of seven sisters and brothers. She had two elder siblings: Emperor Alexander II of Russia and Grand Duchess Maria of Russia; and four younger siblings: Grand Duchess Alexandra of Russia, Grand Duke Constantine of Russia, Grand Duke Nicholas of Russia and Grand Duke Michael of Russia. Attractive, cultured and intelligent, she was considered to be one of the most eligible princesses in Europe. She spoke several languages, and was fond of music and painting. Marriage Olga met Kronprinz Karl of Württemberg in early 1846 in Palermo, Two Sicilies. Her parents wished that she make a dynastic marriage, especially since her siblings Alexander, Maria and Alexandra had married relatively insignificant royal partners. There had already been several marriages between members of the Russian Imperial Family and members of the Württemberg Royal Family (in addition to the marriage between Olga's paternal grandparents): Olga's future father-in-law, King Wilhelm I of Württemberg, married Olga's paternal aunt, Grand Duchess Catherine of Russia; Olga's paternal uncle, Grand Duke Michael of Russia, married Wilhelm I's niece, Princess Charlotte of Württemberg. Olga gave her consent to Karl's proposal of marriage after only a few meetings, on 18 January. The wedding was held in great splendour on 13 July 1846 at the Peterhof Palace, Russia. The couple came back from Russia to the Kingdom of Württemberg on 23 September. They lived mostly in the Villa Berg in Stuttgart and in the Kloster Hofen in Friedrichshafen. The couple had no children,
