When the Nazis came to power in 1933, Hainsfarth still had 34 members of the Jewish community living there. Some of them moved away or emigrated to escape the growing antisemitism but, in 1939, there were still 24 Jews in the village, reduced to eleven by 1941. On 10 August 1942 the Gestapo deported the last ten Jews in Hainsfarth to Theresienstadt, but some were also taken to Piaski. Three more Jews may still have been retained in the village until 1943 as slave labour in a local quarry, but they too were eventually deported. Yad Vashem records at least 50 Jews formerly from Hainsfarth who were killed in the Nazi era. The Jewish community was not restored after the Second World War, with no Jews returning to the village.
