Grand Duke Dmitri Pavlovich of Russia (Russian: Великий Князь Дмитрий Павлович; 18 September 1891 – 5 March 1942) was a son of Grand Duke Paul Alexandrovich of Russia, a grandson of Tsar Alexander II of Russia and a first cousin of Tsar Nicholas II, Marie of Edinburgh (consort of Ferdinand I of Romania), King George II of Greece, King Alexander of Greece, Helen of Greece and Denmark, (second wife of Carol II of Romania), King Paul of Greece, and Prince Philip, Duke of Edinburgh (consort of Queen Elizabeth II).
His early life was marked by the death of his mother and his father's banishment from Russia after marrying a commoner in 1902. Grand Duke Dmitri and his elder sister Grand Duchess Maria Pavlovna, to whom he remained very close throughout his life, were raised in Moscow by their paternal uncle Grand Duke Sergei Alexandrovich and his wife Grand Duchess Elizabeth Feodorovna of Russia, an older sister of Empress Alexandra Feodorovna. His uncle was killed in 1905 and as his aunt entered religious life, Dmitri spent a great deal of his youth in the company of Tsar Nicholas II and his immediate family at the Alexander Palace as they viewed him almost like a foster son.
