Millennialism
A millennium is a period of one thousand years, and, in particular, Christ's thousand-year rule on this earth, either directly preceding or immediately following the Second Coming (and the Day of Judgement).
The millennium reverses the previous period of evil and suffering; it rewards the virtuous for their courage while punishing the evil-doers, with a clear separation of saints and sinners. The vision of a thousand-year period of bliss for the faithful, to be enjoyed here on earth ("heaven on earth"), exerted an irresistible power. Although the picture of life in the millennial era is almost willfully obscure and hardly more appealing than that of, say, the Golden Age, what has made the millennium much more powerful than the Golden Age or Paradise myths are the activities of the sects and movements that it has inspired. Throughout the ages, hundreds of sects were convinced that the millennium was imminent, about to begin in the very near future, with precise dates given on many occasions.
Premillennial sects look for signs of Christ's imminent return. Other chiliast sects, such as the prophetic Anabaptist followers of Thomas Müntzer, have believed that the millennium had already begun, with only their own members having realized this fact. Consequently, they have attempted to live out their own vision of millennial life, radically overturning the beliefs and practices of the surrounding society. In doing so, they offered a model of the good life and expressed their hope that soon the rest of the world would follow and live like they did.
See Christian eschatology for a discussion of "premillennialism" and "postmillennialism".
