Why do movements across history believe the world must end to be saved?

In short: Millenarianism is the belief that society is fundamentally broken and requires a cataclysmic transformation to reach a utopian state. Whether religious or secular, these movements share a conviction that the current order is beyond repair, necessitating a dramatic, often destructive, event to usher in a purified new world.

At its core, millenarianism posits that the status quo is inherently corrupt or unjust. Henri Desroche identified a recurring three-stage pattern in these movements: first, the group experiences increasing oppression; second, they actively resist that oppression; and third, they anticipate a utopian age that liberates the faithful. This framework applies to diverse groups, from 19th-century cargo cults among Pacific Islanders and the Ghost Dance movement of Native Americans to modern secular groups focused on conspiracies or economic collapse.

While the term is often linked to the Christian expectation of a thousand-year Kingdom of God on Earth, its roots are far broader, drawing from Babylonian astrology, Zoroastrianism, and Jewish apocalyptic traditions. Academic usage has evolved; while 'millennialism' often implies a peaceful, thousand-year utopia, 'millenarianism' is increasingly used to describe movements anticipating a more violent, cataclysmic transition. Stephen Jay Gould famously critiqued the interchangeable use of these terms, noting that 'millennium' refers to a thousand-year period, while 'millenarian' derives from a Latin term for 'containing a thousand of anything'.

The implications of these beliefs vary wildly. Many millenarian groups are pacifistic, choosing to withdraw from society in a state of 'world-rejection' to await divine intervention. However, the belief that conventional rules no longer apply can lead to extreme outcomes, including internal violence like the Jonestown tragedy or external terrorism, such as the acts committed by Aum Shinrikyo. Major institutions have long been wary of these ideologies; the Catholic Church, for instance, formally rejects all forms of millenarianism, labeling the attempt to realize messianic hope within history as a 'falsification' and an 'intrinsically perverse' form of secular messianism.
