Baron Roman Nicolaus Maximilian von Ungern-Sternberg (Russian: Барон Ро́берт-Ни́колай-Максими́лиан Рома́н Фёдорович фон У́нгерн-Ште́рнберг) (10 January 1886 NS – 15 September 1921) was an anti-Bolshevik lieutenant general in the Russian Civil War and then an independent warlord whose Asiatic Cavalry Division wrested control of Mongolia from the Republic of China in 1921 after its occupation. He was often referred to as Baron Ungern, or simply Ungern.

Ungern was an arch-conservative pan-monarchist who aspired to restore the Russian monarchy under Grand Duke Michael Alexandrovich of Russia and to revive the Mongol Empire under the rule of the Bogd Khan. In February 1921 he expelled Chinese troops from Mongolia and restored the monarchic power of the Bogd Khan.

In June 1921 he went on to invade East Siberia in support of supposed anti-Bolshevik rebellions and to head off a Red Army-Mongolian partisan invasion; this action led to his defeat and capture two months later. He was taken prisoner by the Red Army and a month later put on trial for counterrevolution in Novonikolaevsk. After a six-hour show trial he was found guilty, and on 15 September 1921 he was executed.

R.F. von Ungern-Sternberg was born in Graz, Austria, in 1886 to a noble Baltic-German family. The Ungern-Sternberg family settled in what is now Estonia during the Middle Ages. Ungern-Sternberg's first language was German, but he was also fluent in French, Russian, English and Estonian. His mother was a German noblewoman named Sophie Charlotte von Wimpffen, later Sophie Charlotte von Ungern-Sternberg, and his father was Baron Theodor Leonhard Rudolph von Ungern-Sternberg (1857–1918). He also had Hungarian roots, and claimed descent from Batu Khan, Genghis Khan's grandson, which will play its role in his dream of reviving the Mongol Empire.
