Answer:
The Zealots had the leading role in the First Jewish–Roman War (66–73 CE). The Zealots objected to Roman rule and violently sought to eradicate it by generally targeting Romans and Greeks.
The Zealots are further blamed for having contributed to the demise of Jerusalem and the Second Temple, and of ensuring Rome's retributions and stranglehold on Judea. The Zealots instigated an almost long-term strive for food between both parties which made them compete for these social amenities overtime.
