Aelia Capitolina (Traditional English Pronunciation: ; Latin in full: ) was a Roman colony founded during Emperor Hadrian's trip to Judaea in 129/130 CE, centered around Jerusalem, which had been almost totally razed after the siege of 70 CE. The foundation of Aelia Capitolina and the construction of a temple to Jupiter at the site of the former temple may have been one of the causes for the outbreak of the Bar Kokhba revolt in 132. Aelia Capitolina remained as the official name until Late Antiquity and the Aelia part of the name transliterated to Īlyāʾ was also used by the Umayyad Caliphate. Name Aelia came from Hadrian's nomen gentile, Aelius, while Capitolina meant that the new city was dedicated to Jupiter Capitolinus, to whom a temple was built. The Latin name Aelia is the source of the much later Arabic term Īlyāʾ (إيلياء), a 7th-century Islamic name for Jerusalem. History Jerusalem, once heavily rebuilt by Herod, was still in ruins following the decisive siege of the city, as part of the First Jewish–Roman War in AD 70. According to Eusebius, the Jerusalem church was scattered twice, in 70 and 135, with the difference that from 70 to 130 the bishops of Jerusalem have evidently Jewish names, whereas after 135 the bishops of Aelia Capitolina appear to be Greeks. Eusebius' evidence for continuation of a church at Aelia Capitolina is confirmed by the Bordeaux Pilgrim. The Roman emperor Hadrian decided to rebuild the city as a Roman colony, which would be inhabited by his legionaries. Hadrian's new city was to be dedicated to himself and certain Roman gods, in particular Jupiter. There is controversy as to whether Hadrian's anti-Jewish decrees followed the Jewish Bar Kokhba revolt or preceded it and were the cause of the revolt. The older view is that the Bar Kokhba revolt, which took the Romans three years to suppress, enraged Hadrian, and he became determined to erase Judaism from the province. Circumcision was forbidden and Jews were expelled from the city. Hadrian renamed Iudaea Province to Syria Palaestina, dispensing with the name of Judaea. Jerusalem was renamed "Aelia Capitolina" and rebuilt in the style of its original Hippodamian plan although adapted to Roman use. Jews were prohibited from entering the city on pain of death, except for one day each year, during the fast day of Tisha B'Av. Taken together, these measures (which also affected Jewish
