As the Second Temple in Jerusalem was destroyed, one of the events commemorated on Tisha B'Av, Judaism fell into crisis with the Sadducee movement falling into obscurity. However, one of the Pharisaic sages Rabbi Yohanan ben Zakkai was smuggled away from Jerusalem in a coffin by his students during the Titus siege. The rabbi obtained permission to establish a Judaic school at Yavne, which became a major center of Talmudic study. This became the crucial mark in the development of Rabbinic Judaism, which would allow Jews to continue their culture and religion without the Temple and essentially even in the diaspora. Despite the upheaval brought by the revolt, and the destruction of the Temple, Jewish life continued to thrive in Judea. Though dissatisfaction with Roman rule eventually led to the Bar Kokhba revolt in 132–136 CE.
