Forced debates between Jews and Christians were a feature of medieval Jewish life, often with dire consequences.

Origins of Polish Jewry (This Week in Jewish History)

This week marks the death anniversary of King Boleslaw V (The Chaste) in 1279.

Jacob Frank and the Burning of the Talmud (This Week in Jewish History)

One of the more colorful false messiahs in Jewish history, Jacob Frank made a career of conversion–first to Islam, then to Christianity, all the while leading a neo-Sabbatean movement that emphasized antinomian “purification through transgression.” His appeal to the Church in 1757 resulted in a modern-day disputation over the Talmud, and ultimately the burning of tens of thousands of precious volumes.

The Dreyfus Affair (This Week in Jewish History)

Wrongly accused of espionage, Captain Alfred Dreyfus was sentenced to Devil’s Island on the basis of remarkably tenuous evidence. May critics, including the famous writer Emile Zola, argued that Dreyfus was unfairly charged simply because he was a Jew in the French army. As evidence mounted that another officer was guilty, the Dreyfus Affair exposed the persistence of pervasive and deep-rooted antisemitism, questioning how effectively Jews were accepted in French society a full century after they were first emancipated.
