Their lives and political authority were so intimately bound up with Temple worship that after Roman legions destroyed the Temple, the Sadducees ceased to exist as a group, and mention of them quickly disappeared from history.

What is the difference between Sadducees and Pharisees?

The Pharisees' Judaism is what we practice today, as we can't make sacrifices at the Temple and instead we worship in synagogues. The Sadducees were the wealthy upper class, who were involved with the priesthood. They completely rejected oral law, and unlike the Pharisees, their lives revolved around the Temple.

Are the Sadducees and Sanhedrin the same?

The composition of the Sanhedrin is also in much dispute, the controversy involving the participation of the two major parties of the day, the Sadducees and the Pharisees. Some say the Sanhedrin was made up of Sadducees; some, of Pharisees; others, of an alternation or mixture of the two groups.
