The
Kitab al Khazari , commonly called the
Kuzari after the
Hebrew name , is one of the most famous works of the medieval
Spanish Jewish philosopher and poet Rabbi
Yehuda Halevi, completed around 1140. Its title is an
Arabic phrase meaning Book of the
Khazars, while the subtitle "The book of refutation and proof on behalf of the most despised religion" shows its purpose and context in medieval Jewish thought.
