A popular assembly was then convened in Jerusalem to formulate policy and decide upon a subsequent course of action. Dominated by the moderate Pharisees, including Shimon ben Gamliel, president of the Sanhedrin, it appointed military commanders to oversee the defence of the city and its fortifications. Leadership of the revolt was thus taken from the Zealots and given to the more moderate and traditional leadership of the Pharisses and Sadducees.
