First Jewish–Roman War: Titus and his armies breach the walls of Jerusalem. (17th of Tammuz in the Hebrew calendar).

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.

The First Jewish–Roman War, also known as the Great Jewish Revolt, the First Jewish Revolt, the War of Destruction, or the Jewish War, was the first of three major Jewish rebellions against the Roman Empire. Fought in the province of Judaea, it resulted in the destruction of Jerusalem and the Jewish Temple, mass displacement, land appropriation, and the dissolution of the Jewish polity.

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.

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.
