mdd > Belarus and Lithuania were parts of the Pale.
of course, all Polish areas occupied by Russia were the Pale, Russia proper did not let Jews in from very early in Moscow history. I don’t think this was the case in other slavic and eastern european lands: Jews settled in Poland, Belorussia, Kievan Rus, Crimea. Not sure, were there any other countries in Eastern Europe who did not allow Jews? (in Western: England for a time)
