The Khazars were a Central Asian people whose king converted to Judaism in the Middle Ages. There is a legend that he called in representatives of Christianity, Judaism, and Islam, in order to decide which religion to choose for himself and the royal family. After listening to each of their arguments, he chose Judaism.[Citation Needed]
Some people believe that many of the Ashkenazi Jews of Europe are descendants of the Khazars. Despite this claim which is often made by anti-semites or anti-zionists, genetic evidence has shown otherwise.
