Hadrian (emperor 117–138 CE) attempted to completely root out Judaism, which he saw as the cause of continuous rebellions. He prohibited the
Torah and the
Hebrew calendar and executed Judaic scholars. The sacred scroll was ceremonially burned on the
Temple Mount. At the former Temple sanctuary he installed two statues, one of
Jupiter, another of himself. In an attempt to erase any memory of Judea or
Ancient Israel, he wiped the name off the map and replaced it with
Syria Palaestina, supplanting earlier terms, such as Judaea. Similarly, he re-established Jerusalem, this time as the Roman
polis of
Aelia Capitolina, and Jews were barred from entering the city, except on the fast day of
Tisha B'Av.

The Jewish–Roman wars had a dramatic impact on the Jews, turning them from a major population in the Eastern Mediterranean into a scattered and persecuted minority. The Jewish–Roman wars are often cited as a disaster to Jewish society.
[11] The defeat of the Jewish revolts altered the Jewish population and enhanced the importance of Jewish diaspora.
