Why did the zealots attack the Romans?

The Zealots didn't attack the Romans. The Romans were going to attack but all the Zealots killed themselves. Over 960 children, men and woman died. Now, that's a different story. They believe the Romans attacked, or were going to attack, because the Zealots would, in a way, pull pranks on the Romans. The Romans got tired of living over 1,000 feet below the Zealots because it also gave the Zealots a advantage at numerous things.Hoped this helped!:)
