And he gathered them together into a place called in the Hebrew tongue Armageddon. And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done.
- Revelation of John 16:16 (KJV)
Armageddon ("Mount of Megiddo") is the site of the final battle between God and Satan in Christian eschatology. Satan will operate through the person known as the "Beast" or the Antichrist, written about in the Book of Revelation. More generally, it can also refer to an apocalyptic catastrophe.
Megiddo was the location of many decisive battles in ancient times. Under Pharaoh Thutmose III, the Ancient Egyptians fought a Canaanite coalition in 15th century BC. Another battle occurred in 609 BC between Egypt and Judea. Later in 1918, the British Empire came into conflict in the same area with the Ottoman Empire.
