Roman Rosen

Rosen graduated from the University of Dorpat and the Imperial School of Jurisprudence,[2] and joined the Russian Foreign Ministry’s Asiatic Department, rising to head the Japan Bureau in 1875. He helped draft the Treaty of Saint Petersburg (1875), in which Japan exchanged its claims over Sakhalin for undisputed sovereignty over the entire Kurile islands chain.[2] He served as First Secretary of the Russian legation at Yokohama from 1875 to 1883. Rosen was then appointed to the Consulate-General of Russia in New York City in 1884, and then as temporary charge d’affaires to Washington, D.C., from 1886 to 1889. In 1891, he opened the Russian legation in Mexico City, remaining in Mexico until 1893. He then returned to Europe, and was appointed ambassador to Serbia, staying in Belgrade until 1897.[2]

During a short term as Russian minister to Tokyo in 1897–1898, Rosen concluded the Nishi-Rosen Agreement between Russia and Japan, whose articles recognized Japanese supremacy in Korea in exchange for an implicit recognition of Russia's exclusive rights to the Kwantung Leased Territory.[2] However, after he was publicly critical over increasing Russian military activity on the Korean coast and the Yalu River, he was suddenly transferred to the rather symbolic post as Ambassador of Russia to the Kingdom of Bavaria in 1899. In 1900 his diplomatic career revived when he exchanged Munich for Greece, and in April 1903 his most important period commenced when he was reinstalled as Minister in Tokyo. Rosen was in Tokyo at the start of the Russo-Japanese War, which he had made every effort to prevent. When United States President Theodore Roosevelt attempted to mediate the hostilities, Rosen was chosen as new Russian ambassador to the United States in May 1905 and as Sergei Witte's deputy within the Russian peace delegation. Rosen traveled to New Hampshire for negotiations in a cessation of hostilities and a peace treaty. The resulting Treaty of Portsmouth was a diplomatic triumph, which ended the war on very favorable terms for Russia.[3]

The large conference table is today preserved at the Museum Meiji Mura in Inuyama, Aichi Prefecture, Japan.

Rosen stayed in the United States until autumn 1911, when he was recalled to St. Petersburg to retire from the diplomatic service. He was subsequently appointed by Tsar Nicholas II to the State Council of Imperial Russia. He held this membership in the Russian parliamentary Upper House under the Constitution of 1905 until the overthrow of the monarchy by the February Revolution in 1917. After the Bolshevik takeover in November 1917 October Revolution and the subsequent persecution of the old political and social elites, Rosen and his family managed to escape from Russia with the help of Western diplomatic friends in the end of the year 1918. He spent his last years in poverty, working as a translator and business consultant.[2]

He got hit by a taxi cab driver while walking down the street on the night of December 14, 1921, in Manhattan, New York City.[4] This crash resulted in the fracture of his shin bone, and despite the fact that he was initially "cheerful[ly] unconcern[ed]" about this crash, Baron Rosen died due to lobar pneumonia resulting from this crash on December 31, 1921, a little more than two weeks after this crash occurred.[2][4]
