A large Russian diaspora also exists all over the world, with notable numbers in the United States, Germany, Israel, and Canada.Russians are the most numerous ethnic group in Europe.The Russians share many cultural traits with their fellow East Slavic counterparts, specifically Belarusians and Ukrainians.They are predominantly Orthodox Christians by religion.
Translations into other languages often do not distinguish these two groups., like the Finnish name for Sweden (Ruotsi), is derived from an Old Norse term for "the men who row" (rods-) as rowing was the main method of navigating the rivers of Eastern Europe, and that it could be linked to the Swedish coastal area of Roslagen (Rus-law) or Roden, as it was known in earlier times.
On some occasions ethnic Russian communities, such as Lipovans who settled in the Danube delta or Doukhobors in Canada, emigrated as religious dissidents fleeing the central authority.
After the Russian Revolution and Russian Civil War starting in 1917, many Russians were forced to leave their homeland fleeing the Bolshevik regime, and millions became refugees.
The same Slavic ethnic population also settled the present-day Tver Oblast and the region of Beloozero.
With the Uralic substratum, they formed the tribes of the Krivichs and of the Ilmen Slavs.
