The spread of Judaism may be called spacial distribution or diaspora.

The spacial distribution of Jews differs from that of any other ethnic religion. This is because Judaism is practiced in many countries, not just its place of origin.

But the spread of Judaism might be caused by diaspora, the action of when the Romans forced Jews to disperse throughout the world. The Romans had forced the diaspora after demolishing an attempt by the Jews to rebel against Roman rule.

Because Jews are a diaspora that live around the world, and anyone with the dedication to do so may convert.

Santeria is an example of the African diaspora.

Typically, they are called Diaspora Jews or Jews of the Diaspora.

Persecution forced the Jews to migrate to new regions.
