The armies of Titus attack the walls of Jerusalem after a six-month siege. Three days later they breach the walls, which enables the army to destroy the Second Temple.

AD 70 (LXX) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Vespasian and Titus. The denomination AD 70 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Titus Caesar Vespasianus was Roman emperor from 79 to 81. A member of the Flavian dynasty, Titus succeeded his father Vespasian upon his death, becoming the first Roman emperor ever to succeed his biological father.

Jerusalem is a city in the Southern Levant, on a plateau in the Judaean Mountains between the Mediterranean and the Dead Sea. It is one of the oldest cities in the world, and is considered holy to the three major Abrahamic religions—Judaism, Christianity and Islam. Both Israel and Palestine claim Jerusalem as their capital city; Israel maintains its primary governmental institutions there, while Palestine ultimately foresees it as its seat of power. Neither claim is widely recognised internationally.

The siege of Jerusalem in 70 CE was the decisive event of the First Jewish–Roman War, a major rebellion against Roman rule in the province of Judaea. Led by Titus, Roman forces besieged the Jewish capital, which had become the main stronghold of the revolt. After months of fighting, they breached its defenses, destroyed the Second Temple, razed most of the city, and killed, enslaved, or displaced a large portion of its population. The fall of Jerusalem marked the effective end of the Jewish revolt and had far-reaching political, religious, and cultural consequences.
