Friedrich Wilhelm Rembert Graf von Berg (, , tr. ; ) was a Baltic German nobleman, statesman, diplomat and general who served in the Imperial Russian Army. Berg was a count of the Austrian Empire and Grand Duchy of Finland and the 5th last man to be promoted General-Field Marshal in the history of the Russian Empire. He served as the Governor-General of Finland from 1854 to 1861 and the last Viceroy of the Kingdom of Poland from 1863 to 1874. Berg was most notable for his role as the viceroy of Finland and Poland. He gained a reputation for his role in defending Finland and Estonia from Anglo-French invasion during the Crimean War and was also crucial in suppressing and crushing the Polish January Uprising of 1863, during which rebel forces carried out numerous failed assassination attempts on him, martial law was consequently declared in Poland. Berg also held responsible for improving the economy and industry of Finland and Poland during his time as viceroy. As a German, Berg was never keen of the Russification policies introduced in Poland, being opposed to the Pan-Slavism ideology of the Russians and keen towards the foreign policies of Germany. Outside of his military career, Berg was also a topographer and geodesist, being one of the founding members of the Russian Geographical Society. He died in St. Petersburg in 1874 and was buried in his family estate in Korten, Livonia (in now Pilskalns, Latvia). Biography Origin Friedrich Wilhelm Rembert von Berg was born on May 15, 1794 (26 according to the Julian calendar in use in Russia at the time), in the family estate in the small village of Sagnitz, in the Kreis Dorpat of the Governorate of Livonia. His father Friedrich Georg von Berg (1763–1811) was a state councillor and his mother Gertruda Wilhelmine von Ermes (1774–1844) was a young noblewoman, the younger Friedrich was the first cousin once removed of generals Gregor (1765–1838) and Burchard Magnus von Berg (1764–1838), both of whom served in the Russian Imperial Army during the course of the Napoleonic Wars. Genealogists still debate where the Livonian noble Berg family originated in, many speculated they originated in Westphalia. The first known ancestor of the family to appear in Livonia was Otto von Berg. His son, who was also named Otto, was a vassal of the Livonian Knighthood. Friedrich belonged to the Sagnitz branch of the Luist line
