The history of the Jewish people is intricate, marked by centuries of migration following their expulsion from Jerusalem and Judea by Titus in 77 AD. They spread throughout the Roman Empire, establishing communities and trade networks, particularly along the Upper Rhine valley. Notable figures, such as Rashi in the 11th century, contributed to Jewish scholarship during this time. The narrative follows Rashi's descendants through the upheaval of the Crusades, which devastated Jewish communities in Alsace and the Upper Rhine. Many sought refuge in the Ghetto of Frankfurt, the Judengasse, where they lived under city and imperial protection for generations. A pivotal moment occurs when one descendant, during the Enlightenment, converts to Christianity, adopting a new identity and founding a new family branch, the Rottensteins. The first generation of Rottensteins emerged as revolutionaries advocating for freedom in Germany, eventually facing exile and dispersing across Europe, with some emigrating to the United States. Their journey mirrors the broader historical developments of their time, showcasing various family branches that achieved scientific and cultural prominence, while others grappled with false claims of origin, ultimately finding success in the modern world.
