676 years ago, on the first day of Nisan 5109 (March 21, 1349), one of the greatest tragedies in Jewish history occurred – the Erfurt Massacre. Approximately 3,000 members of the Jewish community in the German city were murdered in riots that erupted during Sabbath prayers, part of the 1349 persecutions that swept across Europe during the Black Death.
The Black Death – the plague epidemic that ravaged Europe in the 14th century – claimed the lives of tens of millions, but that wasn't the end of it. In the midst of the chaos, blood libels spread accusing Jews of poisoning wells and causing the epidemic. The result was a wave of brutal riots in many cities, including Erfurt, which sealed the fate of entire Jewish communities.
The Jewish community in Erfurt, which was a vibrant center of Torah learning, also lost one of its spiritual leaders that day – Rabbi Alexander Suslin HaCohen, author of "Sefer HaAgudah." Jews who fled the city commemorated the tragedy in lamentations, and one of them, Rabbi Israel of Erfurt, wrote "Zion Aryeh Bechi," a heartbreaking lament about what had occurred.

Beyond the bloodshed, a cultural erasure campaign took place: valuable Hebrew manuscripts were defaced and looted. Some were preserved in various libraries throughout Germany, and later became part of what is now called the "Erfurt Collection."
The Erfurt Massacre was not an isolated event. It was part of a horrific chain of killing sprees, during which tens of thousands of Jews were murdered across Europe in a period of less than two years. The exact numbers are unknown, but estimates range from 50,000 to 100,000 Jews who were murdered or perished in riots, escapes, and mass suicides.
The most severe riots occurred in major cities in Germany, Switzerland, France, and Spain. Jewish communities in many cities were almost completely destroyed, and many Jews were forced to convert or flee to Eastern Europe, especially Poland and Lithuania, where they received more tolerant treatment during that period.
If we thought the Middle Ages were behind us, history reminds us again and again: we are the only ones to stand up for our fate. We are the only ones responsible for ensuring "never again."
