Eschaton

There is an early modern European literature connected to Biblical scholars and ancient near east scholars. The consensus there is to accept Ernst Troelsch's modified "relative deprivation" hypothesis: in both ancient Jewish millenarians, and industrial-revolution-era proletarianizing millenarians, the community's "relative deprivation" spurred them into the hope fulled fantasies of salvation-on-this-earth that subsequently reentered Christian practice.

These were people who, relatively quickly, became relatively worse off than those around them.

Like all over the world, right now.
