There was significant emigration of Swiss people to the Russian Empire from the late 17th to the late 19th century. Rauber estimates that a number of 50,000 to 60,000 Swiss lived in Russia between roughly 1700 and 1917.
Overview
The late 18th and early 19th century saw a flow of Swiss farmers forming colonies such as Şaba, besides specialists of various professions, working as winemakers, cheesemakers, merchants, officers or governesses. The Russian-Swiss generally prospered, partly merging with German diaspora populations. Early Swiss emigrants to Russia were not poor, but brought money with them, establishing themselves as specialist elites, choosing Russia as migration target because it offered greater opportunities for their trades than America. Only in the later 19th century, with Russian industrialization, saw significant migration of lower social classes. Most of these Swiss diaspora populations returned to Switzerland during the interwar period in the wake of the Russian Revolution of 1917, and especially as a result of the Dekulakization under Joseph Stalin during 1929-1931. The most famous Swiss to have lived in Russia are probably the mathematician Leonhard Euler and the military officerFranz Lefort, a close associate of Peter the Great. Lefortovo district in modern Moscow still bears his name. Other notable Russian-Swiss include botanist Johannes Ammann, artist and architect Leonhard Christian Gottlieb Leonardowitsch Schaufelberger, entrepreneur Arnold Schaufelberger, politician Frederic Cesar de la Harpe and general Antoine Henri Jomini in the tsarist period and Fritz Platten and Jules Humbert-Droz in the Soviet period. In 1918, Platten saved Vladimir Lenin's life in St. Petersburg, and in 1923, a Russian-Swiss assassinated Bolshevik leader Vatslav Vorovskii in Lausanne. The Swiss-Russian connection went both ways, and Switzerland was a destination for holidays, studies and exile for Bolsheviks and anti-Bolsheviks alike. Notably, Zürich played host to both Lenin and Aleksandr Solzhenitsyn, and in the years predating the Revolution, up to a third of students at Swiss universities were citizens of Tsarist Russia. Since 1978, the History Department at the University of Zürich under Carsten Goehrke has been assembling an archive of historical documents relating to Swiss emigrants in Russia. The archive collects records of some 5,600 individuals who had come to Switzerland following the collapse of the tsarist state claiming Swiss citizenship, estimated to correspond to about two thirds of the total number. Since the 2000s, there is a renewed limited trend of Swiss farmers emigrating to Russia. In 2006, there was a number of 676 Swiss citizens registered to permanently reside in Russia, or 100 more than in the preceding year.
