Haredi Judaism
Haredi Judaism is not an institutionally cohesive or homogeneous group, but comprises a diversity of spiritual and cultural orientations, generally divided into a broad range of Hasidic sects, Litvishe-Yeshivish streams from Eastern Europe, and Oriental Sephardic Haredim. These groups often differ significantly from one another in their specific ideologies and lifestyles, as well as the degree of stringency in religious practice, rigidity of religious philosophy, and isolation from the general culture that they maintain.
Zealots
Josephus' "Jewish Antiquities" states that there were three main Jewish sects at this time, the Pharisees, the Sadducees, and the Essenes. The Zealots were a "fourth sect", founded by Judas of Galilee (also called Judas of Gamala) in the year 6 CE against Quirinius' tax reform, shortly after the Roman Empire declared what had most recently been the tetrarchy of Herod Archelaus to be a Roman province, and that they "agree in all other things with the Pharisaic notions; but they have an inviolable attachment to liberty, and say that God is to be their only Ruler and Lord." (18.1.6)
