Following the destruction of the Temple, Rome governed Judea through a Procurator at Caesarea and a Jewish Patriarch and levied the Fiscus Judaicus. Yohanan ben Zakkai, a leading Pharisee, was appointed the first Patriarch (the Hebrew word, Nasi, also means prince, or president), and he re-established the Sanhedrin at Yavneh (see the related Council of Jamnia) under Pharisee control. Instead of giving tithes to the priests and sacrificing offerings at the (now-destroyed) Temple, the rabbis instructed Jews to give charity. Moreover, they argued that all Jews should study in local synagogues, because Torah is "the inheritance of the congregation of Jacob" (Deut. 33: 4).

Thus, as the Pharisees argued that all Israel should act as priests, the Rabbis argued that all Israel should act as rabbis: "The rabbis furthermore want to transform the entire Jewish community into an academy where the whole Torah is studied and kept .... redemption depends on the "rabbinization" of all Israel, that is, upon the attainment of all Jewry of a full and complete embodiment of revelation or Torah, thus achieving a perfect replica of heaven." [Neusner, Jacob Invitation to the Talmud: a Teaching Book (1998): 9]
The Rabbinic era itself is divided into two periods. The first period was that of the Tannaim (from the Aramaic word for "repeat;" the Aramaic root TNY is equivalent to the Hebrew root SNY, which is the basis for "Mishnah." Thus, Tannaim are "Mishnah teachers"), the sages who repeated and thus passed down the Oral Torah. During this period rabbis finalized the canonization of the Tanakh, and in 200 Judah haNasi edited together Tannaitic judgements and traditions into the Mishnah, considered by the rabbis to be the definitive expression of the Oral Torah (although some of the sages mentioned in the Mishnah are Pharisees who lived prior to the destruction of the Second Temple, or prior to the Bar Kozeba Revolt, most of the sages mentioned lived after the revolt).
The second period is that of the Amoraim (from the Aramaic word for "speaker") rabbis and their students who continued to debate legal matters and discuss the meaning of the books of the Bible. In Palestine, these discussions occurred at important academies at Tiberias, Caesarea, and Sepphoris. In Babylonia, these discussions largely occurred at important academies that had been established at Nehardea, Pumpeditha and Sura. This tradition of study and debate reached its fullest expression in the development of the Talmudim, elaborations of the Mishnah and records of Rabbinic debates, stories, and judgements, compiled around 400 in Palestine and around 500 in Babylon.

The active period of Pharasaism, the most-influential movement in the development of Orthodox Judaism, extended well into the 2nd and 3rd centuries CE. The Pharisees preserved and transmitted Judaism through the flexibility they gave to Jewish scriptural interpretation in the face of changing historical circumstances. The efforts they devoted to education also had a seminal importance in subsequent Jewish history. After the destruction of the Second Temple and the fall of Jerusalem in 70 CE, the synagogue and the schools of the Pharisees continued to function and to promote Judaism in the long centuries following the Diaspora.
