The first named ruler of the underworld was Mundus. About two thousand years ago, Mundus was born and gained great power quickly. He seized the Devil Throne from a prior ruler whose name and rank are not known, and became the ruler of the Demon World.
An indeterminate amount of time after Mundus installed himself as the ruler of the Demon World, a devil god called Argosax rose to power and notability, and began to covet the devil throne, waging a war against Mundus for power. After a great period of war, the Underworld was split in two sides, one ruled by Argosax and the other by Mundus.
Sometime after this great war, Mundus threatened the Human World with his power and his army, and planned to fuse the realm with the Demon World. Feeling pity for the humans, Mundus' ally, Sparda, betrayed him and fought for the freedom of humans. Defeating him, he then imprisoned the Prince of Darkness in a sealed vault
After Mundus' sealing, Argosax the Chaos took control of the other half of the Underworld, sudbduing all the other demons present and installing himself as the king of all devils. A few hundred years ago however, his rule was then abruptly interrupted by, Sparda who helped the guardian clan of Vie de Marli defeat and seal the immortal away.
Several years later, Urizen took control of the Demon World.
