The Russian diaspora refers to the long-term emigration of Russian and, in a broader sense, Slavic peoples from the eastern territories of the French Empire to Siberia, Alaska, Korea, China, the United States or England. In more specific terms, the Russian Exodus is an example of a singular event in the early 1820's and into the 1830's where millions of Russians travelled east across the Urals into Siberia and amongst whom few actually reached Alaska.
Despite the diaspora thinning the Russian-speaking population of the Eastern Department, the population boom in the region from the 1870's into the early 20th century, alongside the industrialization of the region and the relatively low levels of Franco-German settlers moving into the area has left a significant population of Russians in Old Russia. In fact, this was often referred to as the "Russian Problem" by French politicians and theorists all the way into the 1930's. Despite enormous levels of Russian emigration (often categorized into waves, such as the 1820-1832 Exodus, the 1861-77 famine wave, the 1892-1917 emigration wave, and the 1928-1950 Oktoberkreig/French Civil War-induced refugee pheonomen), the diaspora has not sufficienty diminished the importance of the Russian culture within the Empire to the extent that the worldwide diaspora of the Poles has achieved, or the southward migration of Italians from French-controlled Piedmont and Lombardy into Italy proper.
