Ashkenazi Jews (/ˌæʃ-, ɑːʃkəˈnɑːzi/ ASH-, AHSH-kə-NAH-zee), also known as Ashkenazic Jews or, by using the Hebrew plural suffix -im, Ashkenazim are a Jewish diaspora population who coalesced in the Holy Roman Empire around the end of the first millennium. In the late Middle Ages, due to religious persecution, the majority of the Ashkenazi population shifted steadily eastward, moving out of the Holy Roman Empire into the areas later part of the Polish–Lithuanian Commonwealth, comprising parts of present-day Belarus, Estonia, Latvia, Lithuania, Moldova, Poland, Russia, Slovakia, and Ukraine.
