The Bar Kokhba revolt resulted in the extensive depopulation of Judean communities, more so than during the First Jewish–Roman War of 70 CE. According to Cassius Dio, 580,000 Jews perished in the war and many more died of hunger and disease, 50 fortresses and 985 villages were destroyed. In addition, many Judean war captives were sold into slavery. Some modern historians assert that Dio's numbers were somewhat exaggerated, but other researchers support Dio's claim of massive depopulation. The Jewish communities of Judea were devastated to an extent which some scholars describe as a genocide. However, the Jewish population remained strong in other parts of Palestine, thriving in Galilee, Golan, Bet Shean Valley, and the eastern, southern, and western edges of Judea. Roman casualties were also considered heavy – XXII "Deiotariana" was disbanded after serious losses. In addition, some historians argue that Legio IX Hispana's disbandment in the mid-2nd century could have been a result of this war. In an attempt to erase any memory of Judea or Ancient Israel, Emperor Hadrian wiped the name off the map and replaced it with Syria Palaestina.
