The eminent rishon from medieval France, Shlomo Itzhaki, has had a significant influence on the interpretations of Judaism by Ashkenazim. The Ashkenazi religious rite developed in cities such as Mainz, Worms, and Troyes. Upon their arrival, they adapted traditions carried over from the Holy Land, Babylonia, and the western Mediterranean to their new European environment. The rabbinical term Ashkenazi refers to diaspora Jews who established communities along the Rhine in western Germany and northern France during the Middle Ages. Throughout their numerous centuries living in Europe, Ashkenazim have made many important contributions to its philosophy, scholarship, literature, art, music, and science.

For centuries, Ashkenazim in Europe used Hebrew only as a sacred language until the revival of Hebrew as a common language in 20th-century Israel. Their traditional diaspora language is Yiddish (a West Germanic language with Jewish linguistic elements, including the Hebrew alphabet), which developed during the Middle Ages after they had moved from Germany and France into Northern Europe and Eastern Europe.

' Jews of Germania' Yiddish: אַשכּנזישע ייִדן, romanized: Ashkenazishe Eydn), also known as Ashkenazic Jews or Ashkenazim, are a Jewish diaspora population who coalesced in the Holy Roman Empire around the end of the first millennium CE.
