Driven from Galilee, Zealot rebels and thousands of refugees arrived in Judea, creating political turmoil in Jerusalem. Zealots were at first sealed in the Temple compound. However, confrontation between the mainly Sadducee Jerusalemites and the mainly Zealot factions of the Northern Revolt under the command of John of Giscala and Eleazar ben Simon became evident. With Edomites entering the city and fighting on the side of the Zealots, Ananus ben Ananus was killed and his forces suffered severe casualties. Simon bar Giora, commanding 15,000 troops, was then invited into Jerusalem by the Sadducee leaders to stand against the Zealots, and quickly took control over much of the city. Bitter infighting between factions of Bar Giora, John and Elazar followed through the year 69 CE.
