The Qumran sect's origins are postulated by some scholars to be in the communities of the Hasidim, the pious anti-Hellenistic circles formed in the early days of the Maccabees. The Hasidim may have been the precursors of the Essenes, who were concerned about growing Hellenization and strove to abide by the Torah
Archaeological and historical evidence indicates that Qumran was founded in the second half of the second century B.C.E., during the time of the Maccabean dynasty. The chief sources of information for the history of this fateful time span are the Qumran scrolls and the excavations, but earlier information on the Essenes was provided by their contemporaries: Josephus Flavius, Philo of Alexandria, and Pliny the Elder. Their accounts are continuously being borne out by the site excavations and study of the writings.

The Sadducees included mainly the priestly and aristocratic families; the Pharisees constituted the lay circles; and the Essenes were a separatist group, part of which formed an ascetic monastic community that retreated to the wilderness.
