The Kaifeng Jews, a Mandarin-speaking group from Henan Province, China, experienced first contact with Europeans in 1605 via the religious scholar Matteo Ricci. Modern researchers believe these Jews were descended from Persian merchants who settled in China during the early Song Dynasty. They prospered during the Ming Dynasty as Confucian civil servants, soldiers, and merchants, but they quickly assimilated and lost much of their Jewish heritage. By the beginning of the 19th century, the last rabbi with knowledge of Hebrew died, leaving no successor. The community had become extinct religiously by the late Qing Dynasty due to anti-foreign persecutions brought on by the Taiping Rebellion and Boxer Rebellion. There are a small number of Chinese people today who consider themselves to be descendants of these Jews.
