 Hadrian built a pagan idol on the Temple grounds and prohibited circumcision; these acts of ethnocide provoked the Bar Kokhba revolt 132–136 CE after which the Romans banned the study of the Torah and the celebration of Jewish holidays, and forcibly removed virtually all Jews from Judea.In 200 CE, however, Jews were granted Roman citizenship and Judaism was recognized as a "religio licita" ("legitimate religion") until the rise of Gnosticism and Early Christianity in the fourth century.Following the destruction of Jerusalem and the expulsion of the Jews, Jewish worship stopped being centrally organized around the Temple, prayer took the place of sacrifice, and worship was rebuilt around the community (represented by a minimum of ten adult men) and the establishment of the authority of rabbis who acted as teachers and leaders of individual communities (see Jewish diaspora).
