Former Soviet states, as well as countries that used to be satellite states or territories of the Warsaw Pact, have numerous minority Slavic populations, many of whom are originally from the Russian SFSR, Ukrainian SSR and Byelorussian SSR. As of now, Kazakhstan has the largest Slavic minority population with most being Russians (Ukrainians, Belarusians and Poles are present as well but in much smaller numbers).

Many Slavic populations that were part of the Warsaw Pact are originally from where?
