#1) How did the roman conquest of jerusalem by titus contribute to the growth of diasporic communities?
The Siege of Jerusalem in the year 70 was the decisive event of the First Jewish–Roman War. The Roman army, led by the future Emperor Titus, with Tiberius Julius Alexander as his second-in-command, besieged and conquered the city of Jerusalem, which had been occupied by its Jewish defenders. Jerusalem was sacked and much of the population killed or dispersed. Josephus claims that 1,100,000 people were killed during the siege, of which a majority were Jewish. 97,000 were captured and enslaved. Many fled to areas around the Mediterranean.
