Sometime in the mid-1400s, Rabbi Shlomo Duran of Algiers penned a remarkable teshuvah directed at a group of conversos in Spain. These individuals, who had been forced to embrace Christianity since the 1391 persecutions, had managed to maintain their Jewish faith in secrecy. Their question centered on how they could refrain from the worst forms of chametz on Pesach without drawing the suspicion of the authorities—an endeavor fraught with challenges. This teshuvah touches on many halachic elements regarding chametz and reveals the Marranos' historical struggles in mid-fifteenth-century Spain.

The Marranos’ Secret Pesach

In the 1850s, a groundbreaking innovation was introduced in Galicia: machines to facilitate matzah production. What followed was a fierce and dramatic conflict that shook the Jewish world. Pamphlets were published on both sides, each defending its position with vigor, leading to intense debates over halachah, minhag, and economic policy. In this class, we jump into the heart of the controversy as it played out in the late 1850s—the first phase of this conflict—and then explore how later Chabad sources engaged with this issue.

The Alter Rebbe’s unique script for safrus has a rich and winding history. It has been inked, shelved, revived, and debated—and everyone seems to have an opinion. So, what is the story behind this ksav? What sets it apart? Why do some embrace it wholeheartedly while others remain unsure? This class explores its historical trajectory, some of its writing nuances, and the ongoing conversation around its adoption.

The Story of the Alter Rebbe’s Script

In the mid-12th century, the Almohads swept across North Africa and Spain, driven by a vision of a strictly unified Muslim society. For the Jewish communities under their rule, the choice was stark and unforgiving: convert, flee, or face death. Many outwardly embraced Islam while secretly maintaining their Jewish faith. A rabbi from afar denounced these covert Jews, insisting that their hidden devotion was meaningless. Rambam, however, fiercely rejected this view. In his Igeres Hashmad, he offered a scholarly and compassionate perspective, guiding his brethren through one of the most harrowing dilemmas in Jewish history.

Rambam, the Almohads, and the Secret Jews

In the 1170s, the Jewish community in Yemen faced an existential crisis: a radical ruler forced them to convert to Islam, an apostate Jew spread anti-Jewish propaganda, and a self-declared Messiah sowed confusion. In response, the Rambam penned one of his most powerful letters, offering guidance and encouragement. As we approach the 44th Siyum HaRambam, we revisit this extraordinary letter, its historical context, and its enduring lessons.

Rambam to the Rescue: His Legendary Letter to Yemen

In the 1470s, a series of outrageous blood libels were leveled against Jewish communities in the Germanic lands, including one in Regensburg. To secure their acquittal, the Jews of Regensburg needed an enormous sum of money—far beyond their means. The rabbis gathered in Nuremberg to strategize and ultimately turned to Rabbi Yosef Colon in Pavia with a pressing question: Could they obligate all Jewish communities in the Holy Roman Empire to contribute to helping the Jews in Regensburg? Rabbi Yosef Colon’s response is a masterful work of Talmudic analysis and a sobering reflection on the historical realities of the time.

The Regensburg Blood Libel

On the fifteenth of Shevat, 1348, in the city of Tudela, a man named Yosef performed kidushin with a young woman named Belita. What began as a seemingly ordinary wedding ceremony quickly became a shocking controversy. People who were present asked Belita whether she was truly consenting, and instead of her confirming, it was her father who spoke on her behalf. Further investigation revealed that Belita had previously stated her refusal to this marriage not once but twice, and, in fact, was already married to her uncle Avraham. To complicate matters, she was also engaged to a third man! On the eve of the Black Death sweeping through Europe, this tangled web of relationships turned into a halachic dilemma that ultimately reached the desk of Rabbi Yehudah, son of the Rosh.

The Scandalous Marriage, 1348

Rabbi Shlomo ben Aderes, the legendary rabbi and leader of Barcelona, received countless questions during his tenure, many of which have been preserved to this day. In this class, we discuss six compelling cases of tax disputes. They reveal remarkable insights into the political and economic realities of the time, the dynamics within Jewish communities, and their interactions with the surrounding non-Jewish world.

Taxes and Tensions: The Story of Jewish Tax Disputes in Medieval Spain

The book known as Yosifun, cherished in traditional Jewish circles, and the books of Josephus, preserved in Greek and Latin by non-Jewish hands, spark challenging questions about authorship, reliability, and reconstructing the Jewish past. This class explores how rabbis throughout the ages evaluated these works, their role on the Jewish bookshelf, and how to navigate the apparent discrepancies between their accounts and the teachings of chazal.

Josephus

The Books of Maccabees tell the dramatic story of the Chanukah revolt and the heroism of the Jewish fighters. But who wrote these books, and why were they left off the Jewish bookshelf? We’ll discuss the history of these texts, explore their reception among Jews throughout the ages, and probe the role they played—or didn’t play—in shaping Jewish memory of the Chanukah story.
