Roman von Ungern-Sternberg

Baron Nikolai Robert Maximilian Freiherr von Ungern-Sternberg (Russian: Роман Фёдорович фон Унгерн-Штернберг, romanized: Roman Fyodorovich fon Ungern-Shternberg; 10 January 1886 – 15 September 1921), often referred to as Roman von Ungern-Sternberg or Baron Ungern, was a Russian military leader in the Russian Civil War and then an independent warlord who intervened in Mongolia against China. Part of the Russian Empire's Baltic German minority, Ungern was an ultraconservative monarchist who aspired to restore the Russian monarchy after the 1917 Russian Revolution and to revive the Mongol Empire under the rule of the Bogd Khan.
