Apocalypticism is the religious belief that the end of the world is imminent, even within one's own lifetime. This belief is usually accompanied by the idea that civilization will soon come to a tumultuous end due to some sort of catastrophic global event. Apocalypticism is one aspect of eschatology in certain religions—the part of theology concerned with the final events of history, or the ultimate destiny of humanity.
The religious versions of these views and movements often focus on cryptic revelations about a sudden, dramatic, and cataclysmic intervention of God in history; the judgment of humanity; the salvation of the faithful elect; and the eventual rule of the elect with God in a renewed heaven and earth. Arising initially in Zoroastrianism, apocalypticism was developed more fully in Judaic, Christian, and Islamic eschatological speculation.
Apocalypticism is often conjoined with the belief that esoteric knowledge will likely be revealed in a major confrontation between good and evil forces, destined to change the course of history. Apocalypses can be viewed as good, evil, ambiguous or neutral, depending on the particular religion or belief system promoting them. However, it is not exclusively a religious idea and there are end times or transitional scenarios based in modern science, technology, political discourse, and conspiracy theories.
