The Jews in Belarus, then known as Byelorussian SSR were the third largest ethnic group in the country in the first half of the 20th century. Before World War II, Jews were the third among the ethnic groups in Belarus and comprised more than 40% of the population in cities and towns. The population of cities such as Minsk, Pinsk, Mahiliou, Babrujsk, Viciebsk, and Homiel was more than 50% Jewish. In 1897 there were 724,548 Jews in Belarus, or 13.6% of the total population. Some 800,000 Jews—90% of the Jewish population—were killed in Belarus during the Holocaust. According to the 2009 census, there were 12,926 Jews in Belarus (0.1% of the population). The Jewish Agency estimates the community of Jews in Belarus at 70,000. Marc Chagall, Mendele Mocher Sforim, Chaim Weizmann and Menachem Begin were born in Belarus. By the end of the 19th century, many Belarusian Jews were part of the general flight of Jews from Eastern Europe to the New World due to conflicts and "pogroms" engulfing the Russian Empire and the anti-Semitism of the Russian "czars". Millions of Jews, including tens of thousands of Jews from Belarus, emigrated to the United States of America and South Africa. A small number also emigrated to the British Mandate of Palestine. During the first years of Soviet occupation of Belarus, Jews were able to get managing positions in the country.
