Rabbinic Judaism (Hebrew: יהדות רבנית, romanized: Yahadut Rabanit), also called Rabbinism, Rabbinicism, Rabbanite Judaism, or Talmudic Judaism, is rooted in the many forms of Judaism that coexisted and together formed Second Temple Judaism in the land of Israel, giving birth to classical rabbinic Judaism, which flourished from the 1st century CE to the final redaction of the Talmud in c. 600. Mainly developing after the destruction of the Jerusalem Temple (70 CE), it eventually became the normative form of Judaism.
Rabbinic Judaism has been an orthodox form of Judaism since the 6th century CE, after the codification of the Babylonian Talmud. It has its roots in the Pharisaic school of Second Temple Judaism and is based on the claim that Moses at Mount Sinai received both the Written Torah (Torah she-be-Khetav) and the Oral Torah (Torah she-be-al Peh) from God. The Oral Torah explains the Written Torah, and the rabbis claimed that it was they who possessed this memorized and orally transmitted part of the divine revelation. At first, it was forbidden to write down the Oral Torah, but after the destruction of the Second Temple, it was decided to write it down in the form of the Talmud and other rabbinic texts for the sake of preservation.
