Rabbinic Judaism, also known as Talmudic Judaism, takes its name from the Talmud, a collection of rabbinic teachings, both in the form of a commentary on the Mishnah and a commentary on the Bible, written in the 5th-7th centuries.
Judaism in the Talmudic form was accepted as valid by virtually all Jews (the Talmud was not recognized by the Karaites). Rabbinic Judaism became the basis for all later branches of Judaism.
