1615 April 20, (21 Nissan 7th day of Passover) JEWS BANISHED FROM WORMS (Germany)
With the encouragement of the Guilds, the Jews were forced from the city during the holiday and the synagogue destroyed. The following year on January 20, (1st of Sh'vat, 5376) they were allowed to return to their homes and rebuild the synagogue. The community instituted a public fast day to be held each year on the last day of the month of Tevet (the month before Sh’vat). This commemoration remained in effect for generations.
