Zealots

From the word "zeal"

They were passionate about Jewish political independence.

Very militant and known for starting revolts (they thought that the Messiah would be a military leader)

Angry with the Sadducees and anyone who paid taxes to Rome

They began the Jewish Revolt around 66 AD and eventually are all killed off alongside the Sadducees

Some historians think that Judas was a zealot, since "Iscariot" means "dagger-carrier"
