Judaism
Around the 1st century CE, there were several small Jewish sects: the Pharisees, Sadducees, Zealots, Essenes, and Christians. After the destruction of the Second Temple in 70 CE, these sects vanished. Christianity survived, but by breaking with Judaism and becoming a separate religion; the Pharisees survived but in the form of Rabbinic Judaism (today, known simply as "Judaism"). The Sadducees rejected the divine inspiration of the Prophets and the Writings, relying only on the Torah as divinely inspired. Consequently, a number of other core tenets of the Pharisees' belief system (which became the basis for modern Judaism), were also dismissed by the Sadducees. (The Samaritans practiced a similar religion, which is traditionally considered separate from Judaism.)
Anti-Zionism
Most Orthodox religious groups have accepted and actively support the State of Israel, even if they have not adopted "Zionist" ideology. The World Agudath Israel party (founded in Poland) has at times participated in Israeli government coalitions. Most religious Zionists hold pro-Israel views from a right-wing viewpoint. The main exceptions are Hasidic groups such as Satmar Hasidim, which have about 100,000 adherents worldwide, as well as numerous different, smaller Hasidic groups, unified in America in the Central Rabbinical Congress of the United States and Canada and in Israel in the Edah HaChareidis.
