This is the thesis of Jacob Neusner, which has won increasing acceptance. Out of Neusner’s many writings, the following are especially useful for this topic: Judaism: The Evidence of the Mishnah (Chicago: Univ. of Chicago Press, 1981); “The Formation of Rabbinic Judaism: Yavneh (Jamnia) from A.D. 70–100,” in Aufstieg und Niedergang der Römischen Welt II.19.2, ed. H. Temporini and W. Hasse (Berlin and New York: de Gruyter, 1979), pp. 3–42.
