1. Question :
Are there any accounts by Greek, or other historians, that detail what happened to the Sadducees, who were tied to Temple in Jerusalem?
Was there a persecution of the Sadducees?
I am asking this question here - rather than Judaism.SE because I am hoping to find secular historical accounts, if possible ...
The Sadducees were a political sect in Israel, defending their authority against the newer sect of the Pharisees (which later became known as Rabbinicism). As a result, it is difficult to rely on the authority of Pharasaic/Rabbinic sources.
About a millennia after the Temple Period, Maimonides' declared that that they could be killed, on sight, without trial :
Mishneh Torah, Mamrim 3:1-3 : 1 A person who does not acknowledge validity of the Oral Law is not the rebellious elder mentioned in the Torah. Instead, he is one of the heretics and he should be put to death by any person. ... 3 To whom does the above apply? To a person ... as did Tzadok and Beitus and those who erred in following them.
