In Christianity, the War in Heaven portrays a clash between the archangel Michael and Lucifer, who was once a high-ranking angel but rebelled against God due to his pride and ambition. This rebellion sparked a celestial battle in heaven, where Michael led the loyal angels in defense of God's sovereignty against Lucifer and his followers.

The conflict symbolizes the struggle between good and evil, with Michael representing divine righteousness and Lucifer embodying the forces of darkness and rebellion. Michael and the loyal angels emerged victorious, leading to the expulsion of Lucifer, now known as Satan, and his followers from heaven.

Following their banishment, Satan and his rebel angels (demons) were cast down to earth, where they continue their opposition against God and humanity. To this very day.
