Destruction of the Second Temple - Wikipedia

In 66 CE the Jewish population rebelled against the Roman empire. Four years later, in 70 CE, Roman legions under Titus retook and subsequently destroyed much of Jerusalem and the Second Temple. The Arch of Titus, located in Rome and built to commemorate Titus's victory in Judea, depict a Roman victory procession with soldiers carrying spoils from the Temple, including the Menorah. Although Jews continued to inhabit the destroyed city, Jerusalem was razed by the Emperor Hadrian at the end of the Bar Kokhba revolt in 135 CE when he established a new city called Aelia Capitolina. The destruction date according to the Hebrew calendar was the 9th of Av, also known as Tisha B'Av (29 or 30 July 70).
