Inherent in the later traditions, and indeed, in most modern scholarly treatments, is the
assumption that the Pharisees bequeathed their traditions to the tannaim. The terms
“Pharisees” and “tannaim” overlap chronologically. We speak of Pharisaic Judaism as
emerging in the early Hasmonean period, around 150 B.C.E., and continuing up to the
destruction of the Temple in 70 C.E., when it was succeeded by tannaitic Judaism. Yet
the transition was not an immediate, sudden break. In order to understand how the
development from Pharisees to tannaim took place, we must ask what typified the
Pharisee and what typified the tanna. In what ways were they the same, and in what ways
were they different?
The Pharisees were lay sages of the Torah who were only informally organized. Even
before the days of the preeminent sages Hillel and Shammai, the Pharisees had made the
transition from being a political force in the Hasmonean coalition to being a group of
religious leaders, loosely joined together by the same interpretation of Judaism, who
sought to teach their approach to the people at large. They did not see the collection,
arrangement, or passing on of traditions as their function, nor were they an organized
bureaucracy.
The tannaim, on the other hand, involved themselves in the systematic collection and
transmission of traditions, and their efforts eventually culminated in the redaction of the
Mishnah. (The very name tanna is Aramaic for a memorizer and reciter of traditions.)
The tannaim belonged to schools (sometimes called academies) that were more
formalized than those of the earlier Pharisees, and they sought to expand and to organize
them.
A final, fundamental difference has to do with the concept of an oral law. Pharisaism
traced its nonbiblical legal and exegetical traditions to the tradition of the fathers” or
“unwritten laws.” Yet nowhere do we find the Pharisees asserting that these traditions
came from Sinai. The tannaim, as we will soon see, asserted that their extrabiblical
traditions, many of them inherited from the Pharisees, were part of the oral law, a second
Torah given by God to Moses at Sinai along with the written law.
The evolution from the era of the Pharisees to that of the tannaim, like the later
transition from tannaim to amoraim (the teachers of the Talmud [Gemara], ca. 200–500
C.E.), required time to allow for the necessary innovations as well as for organic
development. Various external causes helped to foster the change. The desire to gather
traditions and standardize Judaism was brought about by the Great Revolt of 66–73 C.E.
and by the notion that the defeat was partly the result of the sectarian strife that had
plagued the Jewish people in the years leading up to the revolt and even during the war.
The tendency toward more organized schools replacing the informal circles of Pharisaic
times was encouraged to some extent by the new status which the tannaitic academy was
granted by the Roman overlords. The rise of a bureaucracy and the role of tannaim as
judges throughout the land resulted from the new political situation. Finally, the desire to
collect and preserve traditions is always strengthened in periods after wars and catastrophes, a pattern which can be observed repeatedly in the ancient Near East.
