The Jews were dispersed outside Judea. Jews moved to Cyrenaica, Egypt, Cyprus and Mesopotamia. These displaced Jews continued their uprising against the Romans which led to the Second Jewish-Roman War also known as Kitos War. The Jews were led by Lukuas in this revolt. Unluckily, the Jews were again defeated by the Romans. This time, the captured Jews were enslaved or banished. The Romans became more hostile; they banned the Torah; sought and executed the rabbis and Jewish scholars.
The third and final war of the Romans and the Jews was called Bar Kokhba Revolt because it was led by Simon Bar Kokhba in 132 CE. This war lasted for three violent years and ended with the more massive diaspora of the Jews following their defeat. This time the Jews were totally forbidden in their homeland, so they were really scattered in various parts of the earth. Luckily, they were able to settle and find jobs in the places where they transferred.
Jews continued experiencing tortures, expulsions and killings even after their dispersion from their homeland. With the proliferation of Christianity between the 11th and 13th centuries, the Crusaders, wiped out the entire population of Jews in Jerusalem by burning and/ or killing them. In the 18th century, the Jews were allowed to become citizens in France and the US through the American Revolution. More and more countries started accepting the Jews in their territories as the years go by. But in the 20th, the Nazi forces executed around six million Jews during the Holocaust known as the pogrom, forcing again the Jews to be dispersed from the lands where they have previously sought refuge.
The diaspora is an earlier form of racial discrimination or even worst. They had experienced being looked upon, maltreated, persecuted, exiled deprived of their freedom and their basic rights. They were mistreated due to some rumors or misinformation spread against them. They were accused of killing Christian babies and used their blood in making bread, and they were also accused of killing Jesus Christ. Up until now, diaspora still continues in some parts of the world now, not necessarily to the Jews but also for people who were ostracized or exiled.
The Jewish diaspora gave many lessons to the Jews. Today, they are still scattered all over the world, even if they are already allowed to return to their homeland. Had they not dispersed before, they might not have thrived the way they are flourishing now.
