"The Pharisees (/ˈfærəsiːz/; Hebrew: פְּרוּשִׁים Pərūšīm) were a social movement and a school of thought in the Levant during the time of Second Temple Judaism. After the destruction of the Second Temple in 70 CE, Pharisaic beliefs became the foundational, liturgical, and ritualistic basis for Rabbinic Judaism.
Conflicts between Pharisees and Sadducees took place in the context of much broader and longstanding social and religious conflicts among Jews, made worse by the Roman conquest. Another conflict was cultural, between those who favored Hellenization (the Sadducees) and those who resisted it (the Pharisees). A third was juridico-religious, between those who emphasized the importance of the Second Temple with its rites and services, and those who emphasized the importance of other Mosaic Laws. A fourth point of conflict, specifically religious, involved different interpretations of the Torah and how to apply it to current Jewish life, with Sadducees recognizing only the Written Torah (with Greek philosophy) and rejecting doctrines such as the Oral Torah, the Prophets, the Writings, and the resurrection of the dead." - (en.wikipedia.org 10.08.2021)
