In 1509, Emperor Maximilian of Germany ordered that all Jewish books in the cities of Cologne and Frankfurt am Main be destroyed. This followed the request of Pfefferkorn, a baptized Jew, who claimed that Jewish literature was insulting to Christianity. The Jews appealed to the Emperor to reconsider this edict, and Maximilian agreed to investigate the matter. He appointed Johann Reuchlin, a famed German scholar, to conduct the investigation. The report issued by Reuchlin was very positive. He demonstrated that the books openly insulting to Christianity were very few and viewed as worthless by most Jews themselves. The other books were needed for Jewish worship, and contained much value in the areas of theology and science.
The Emperor rescinded his edict on the 14th of Sivan, 1510.
It is the custom of many communities (and such is the Chabad custom) to continue the weekly study of a chapter Ethics of the Fathers ("Avot"), one chapter each Shabbat afternoon, through through the summer, until the Shabbat before Rosh Hashanahn (the first six-week cycle is completed on the six Shabbatot between Passover and Shavuot). This Shabbat, being the first Shabbat after Shavuot, we study Chapter One.
