Zealots

a sect of Jews which originated with Judas the Gaulonite (Acts
5:37). They refused to pay tribute to the Romans, on the ground
that this was a violation of the principle that God was the only
king of Israel. They rebelled against the Romans, but were soon
scattered, and became a lawless band of mere brigands. They were
afterwards called Sicarii, from their use of the sica, i.e., the
Roman dagger.
