Jewish revolt against he Romans.

The Bar Kokhba revolt (132–136; Hebrew: מרד בר כוכבא‎ or mered bar kokhba) against the Roman Empire was the third major rebellion by the Jews of Iudaea Province (also spelled Judaea) and the last of the Jewish-Roman Wars. Simon bar Kokhba, the commander of the revolt, was acclaimed as a Messiah, a heroic figure who could restore Israel. The revolt established an independent state of Israel over parts of Judea for over two years, but a Roman army of 12 legions with auxiliaries finally crushed it. The Romans then barred Jews from Jerusalem, except to attend Tisha B'Av. Jewish Christians hailed Jesus as the Messiah and did not support Bar Kokhba. They were barred from Jerusalem along with the rest of the Jews. The war and its aftermath helped differentiate Christianity as a religion distinct from Judaism, see also List of events in early Christianity. The revolt is also known as The Second Jewish-Roman War, The Second Jewish Revolt, The Third Jewish-Roman War or The Third Jewish Revolt (counting the Kitos War, 115 - 117, as second).
Background

After the failed Great Jewish Revolt in the year 70, the Roman authorities took measures to suppress the rebellious province. Instead of a procurator, they installed a praetor as a governor and stationed an entire legion, the X Fretensis. Because the Revolt had resulted in the destruction of Jerusalem, the Sanhedrin at Yavne provided spiritual guidance for the Jewish nation, both in Judea and throughout the Jewish diaspora.

In 130, Emperor Hadrian visited the ruins of Jerusalem. At first sympathetic towards the Jews, Hadrian promised to rebuild the city, but the Jews felt betrayed when they found out that his intentions were to rebuild the Jewish holiest city as a Roman metropolis, and a new temple upon the ruins of the Second Temple, which was to be dedicated to Jupiter.

An additional legion, the VI Ferrata, was stationed in the province to maintain order, and the works commenced in 131 after the governor of Judaea Tineius Rufus performed the foundation ceremony of Aelia Capitolina, the city’s projected new name. "Ploughing up the Temple" was a religious offence that turned many Jews against the Roman authorities. The tensions grew higher when Hadrian abolished circumcision (brit milah), which he, a Hellenist, viewed as mutilation. A Roman coin inscribed Aelia Capitolina was issued in 132.
