After the failed revolution by Bar Kokhba in 132–135 CE, the Romans put down the revolt, and the emperor Hadrian tried to put a permanent end to the Sanhedrin. According to the Talmud, Hadrian decreed that anyone who gave or accepted "semikhah" would be killed, any city in which the ceremony took place would be razed, and all crops within a mile of the ceremony's site would be destroyed. The line of succession was saved by Rabbi Judah ben Bava, who took five students of the recently martyred Rabbi Akiva to a mountain pass far from any settlement or farm, and ordained all five students. When the Romans attacked them, Rabbi Yehuda blocked the pass with his body allowing the others to escape, and became one of Judaism's ten Rabbinic Martyrs himself by being speared 300 times. The five new rabbis – Rabbi Meir, Rabbi Shimon, Rabbi Yehudah, Rabbi Yose and Rabbi Eleazar ben Shammua – escaped and became the next generation of Torah leadership.
