zaltzvasser – Russian rule of Poland and Lithuania began in the 1700s and ended in the 1900s. You couldn’t possibly expect that after over 100 years of oppressive Czarist anti-Jewish rule that all the women would suddenly start covering their hair again properly as soon as the Russians were kicked out.
Mir was part of the Russian Empire until 1920. And it became part of Russia (USSR) again in 1939. Mir was only part of Poland between 1920 and 1939. There was no country Poland for over a hundred years until 1920. Rebt. Shain went there only eleven years after the Russians left and she left Mir just two years before the Russians took it over again. Just a few short years after the Russians left for only a brief period, it isn’t reasonable to have expected everyone to have adjusted from a hundred plus years of oppressive religious rule.
