Maria's father Maximilian de Beauharnais, 3rd Duke of Leuchtenberg had traveled to St. Petersburg, eventually winning the hand of Grand Duchess Maria Nikolaevna, Nicholas I's eldest daughter. Maximilian was subsequently bestowed with the style Imperial Highness and given the title Prince Romanowsky. As the daughter of a Russian grand duchess, Maria and her siblings were always treated as grand dukes and duchesses, bearing the styles Imperial Highness. After their father's death in 1852, their mother morganatically remarried to Count Grigori Stroganov two years later. As this union was kept secret from her father Emperor Nicholas I, Grand Duchess Maria was forced into exile abroad. Alexander felt sympathy for his sister however, and paid special attention to her children from her first marriage, who lived in St. Petersburg without their mother.
1866 assassination attempt
On 4 April 1866, Maria and her brother Nicholas were accompanying their uncle Alexander in St. Petersburg, when an assassination was attempted. Alexander stopped to put on an overcoat before climbing into his carriage, when a man quickly aimed a pistol at him; only the swift action of a man named Komissaroff, who knocked the man's hand up in the air, saved the emperor's life.
After her marriage, Maria spent most of her time in Germany, paying only rare visits to Russia. As a new wife, Maria began her duties soon after marrying, for instance representing her husband's relative Grand Duchess Louise of Baden at the christening of the Prince of Leiningen's daughter. During the Franco-Prussian War, Wilhelm served with the Prussian army under the command of Wilhelm I. On 29 July, Maria and her husband stayed with Crown Prince Frederick, and according to the prince's memoirs, "distracted us for the moment from the anxieties of the present". Prince Wilhelm died on 27 April 1897. After his death, Maria founded a new organization, called the German Anti-Immorality Association. Its purpose was to suppress "vice among the upper classes". Maria, with the help of Grand Duchess Eleonore of Hesse and Queen Charlotte of Württemberg, set aside a fund meant to produce pamphlets persuading both female and male royal figures that their prominent roles in society meant they should be examples of moral purity. They also sent a missive to their family and friends asking them to "abstain from immorality" for one year. Princess Maria remained widowed until her own death, on 16 February 1914 in St. Petersburg. As with the court of St. Petersburg, Maria's death cast the Berlin court into mourning, disrupting planned court festivities.
