Siege of Jerusalem (70 CE)

The siege of Jerusalem of 70 CE was the decisive event of the First Jewish–Roman War (66–73 CE), in which the Roman army led by future emperor Titus besieged Jerusalem, the center of Jewish rebel resistance in the Roman province of Judaea. Following a five-month siege, the Romans destroyed the city and the Second Jewish Temple.

In April 70 CE, three days before Passover, the Roman army started besieging Jerusalem. The city had been taken over by several rebel factions following a period of massive unrest and the collapse of a short-lived provisional government. Within three weeks, the Roman army broke the first two walls of the city, but a stubborn rebel standoff prevented them from penetrating the thickest and third wall. According to Josephus, a contemporary historian and the main source for the war, the city was ravaged by murder, famine, and cannibalism.

On Tisha B'Av, 70 CE (August 30), Roman forces overwhelmed the defenders and set fire to the Temple. Resistance continued for another month, but eventually the upper and lower parts of the city were taken as well, and the city was burned to the ground. Titus spared only the three towers of the Herodian citadel as a testimony to the city's former might. The siege had a major toll on human life, with many people being killed and enslaved, and large parts of the city destroyed. This victory gave the Flavian dynasty legitimacy to claim control over the empire. A triumph was held in Rome to celebrate the conquest of Jerusalem, and two triumphal arches were built to commemorate it. The treasures looted from the Temple were put on display.

The destruction of Jerusalem and the Second Temple marked a major turning point in Jewish history. The loss of mother-city and temple necessitated a reshaping of Jewish culture to ensure its survival. Judaism's Temple-based sects, including the priesthood and the Sadducees, diminished in importance. A new form of Judaism that became known as Rabbinic Judaism developed out of Pharisaic school and eventually became the mainstream form of the religion. Many followers of Jesus of Nazareth also survived the city's destruction. They spread his teachings across the Roman Empire, giving rise to the new religion of Christianity. After the war had ended, a military camp of Legio X Fretensis was established on the city's ruins. Jerusalem was later re-founded as the Roman colony of Aelia Capitolina. Foreign cults were introduced and Jews were forbidden entry. This event is often considered one of the catalysts for the Bar Kokhba revolt.
