The sectarians, who had divorced themselves from the main body of the Jewish people, espoused fervent messianic beliefs. After having left Jerusalem following a harsh dispute with the Jerusalem priesthood regarding theological and ritual matters, it became their goal to return to the city in order to restore the "desolate" Temple (as they perceived it). The question of when the sectarians first began to settle in Qumran is still the subject of much debate. It is now commonly accepted that the sect's founder, an unknown personality referred to in the scrolls as the "Teacher of Righteousness," established the community in the second half of the 2nd century BCE. As for its end, the general consensus is that the community met its fate in 68 CE, when the Roman army destroyed the settlement on its way to suppressing the revolt that had broken out in Jerusalem (later to be known as the Great Revolt).
