Provinces of the Roman Empire involved in the Diaspora Revolt
Provinces of the Roman Empire involved in the Diaspora Revolt

The Diaspora Revolt (115–117 CE) was a series of uprisings by Jewish diaspora communities across the eastern Roman Empire during the reign of Emperor Trajan. The uprisings erupted nearly simultaneously in Egypt, Cyrenaica and Cyprus, amid tensions following the destruction of the Jerusalem Temple, the imposition of the Fiscus Judaicus tax, messianic expectations, hopes for a return to Judaea, and Trajan's engagement with the Parthian campaign in Mesopotamia. Roman forces under generals Marcius Turbo and Lusius Quietus suppressed the revolts. The conflict resulted in the destruction of Jewish communities in multiple regions.

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
