According to Mark Burgess (a Center for Defense Information research analyst), the 1st century Jewish political and religious movement called Zealotry was one of the first examples of the use of terrorism by Jews. They sought to incite the people of Judaea Province to rebel against the Roman Empire and expel it from Israel by force of arms. The term Zealot, in Hebrew kanai, means one who is zealous on behalf of God. The most extremist groups of Zealots were called Sicarii. Sicarii used violent stealth tactics against Romans. Under their cloaks they concealed sicae, or small daggers, from which they received their name. At popular assemblies, particularly during the pilgrimage to the Temple Mount, they stabbed their enemies (Romans or Roman sympathizers, Herodians), lamenting ostentatiously after the deed to blend into the crowd to escape detection. In one account, given in the Talmud, Sicarii destroyed the city's food supply so that the people would be forced to fight against the Roman siege instead of negotiating peace. Sicarii also raided Jewish habitations and killed fellow Jews whom they considered apostates and collaborators.
