Armageddon

Armageddon (Greek αρμαγεδδωνarmageddôn] also spelled Har-Magedon in some modern English translations) is the final climactic battle between God, also known as YHWH Elohim, and Satan the Devil, written in the Book of Revelation in the Christian New Testament, or more generally, an apocalyptic catastrophe.

The word Armageddon in Scripture is known only from a single verse in the Greek New Testament, where it is said to be Hebrew, but it is thought to represent the Hebrew words Har Megido (הר מגידו), meaning "Hill of Megiddo". Megiddo was the location of many decisive battles in ancient times (see Battle of Megiddo).

Before the Second World War, the First World War was commonly referred to in newspapers and books as "Armageddon", in addition to "the Great War".
