Under one word "Jews" completely different peoples unite! Not all Jews are descended from ancient Jews! There are Jews who descended from other peoples who converted to Judaism. For example, from the Khazars, Turks and Slavs who converted to Judaism. The origin of the Jews from the Slavs is almost unknown in the world. In the Jewish environment itself, these questions are shyly hushed up. In his new book, Michael Dorfman also talks about the secrets of Ashkenazi Jews. And about what contribution this little active people made to the culture of the whole world.
