There were several reasons why there was conflict between the Romans and the Jews:
Religious and cultural differences: The Romans were a polytheistic society with a pantheon of gods, while the Jews were monotheistic and worshipped only one God. This fundamental difference in religious belief often led to tension between the two groups, especially as the Romans sought to impose their own religious practices on the Jews. For example, the Roman governor of Judea, Pontius Pilate, tried to set up Roman standards in Jerusalem, which the Jews viewed as an affront to their religion.
Political tensions: The Romans saw themselves as the dominant power in the region and sought to impose their rule on the Jewish people. This often led to clashes between the two groups, as the Jews resisted Roman rule and sought to maintain their independence. The Romans viewed the Jews as a rebellious people and often used force to maintain control, which only served to exacerbate the tensions between the two groups.
Economic factors: The Jewish people were an important trading community in the region, and their wealth and prosperity often made them a target for Roman taxation and exploitation. The Romans viewed the Jews as a source of revenue and often imposed heavy taxes on them, which only served to increase the economic tensions between the two groups. This economic exploitation, coupled with the other factors mentioned above, created a volatile situation that often led to conflict between the Romans and the Jews.
