Millenarianism or millenarism (from Latin millenarius 'containing a thousand' and -ism) is the belief by a religious, social, or political group or movement in a coming fundamental transformation of society, after which "all things will be changed".
[6] Stephen Jay Gould has argued that this usage is incorrect, stating: Millennium is from the Latin mille, "one thousand," and annus, "year"—hence the two n's.
A core doctrine in some variations of Christian eschatology is the expectation that the Second Coming is very near and that there will be an establishment of a Kingdom of God on Earth.
[9] According to an interpretation of biblical prophecies in the Book of Revelation, this Kingdom of God on Earth will last a thousand years (a millennium) or more.
[11] Many if not most millenarian groups claim that the current society and its rulers are corrupt, unjust, or otherwise wrong, and that they will soon be destroyed by a powerful force.
Millenarian ideologies or religious sects sometimes appear in oppressed peoples, with examples such as the 19th-century Ghost Dance movement among Native Americans, early Mormons,[15] and the 19th and 20th-century cargo cults among isolated Pacific Islanders.
