Origin
Along with his sister Umar, Dormammu was exiled for unknown reasons from the realm of their birth in the Faltine Dimension.  The two sought sanctuary within the Dark Dimension, a pocket cosmos where the laws of reality are arbitrary.  Against the council of the realms sorcerers, they were given positions of power by the ruler Oinar in exchange for knowledge of how to breach the dimensional barriers that separate realties, therefore expanding the sorcerer-king's domain.

Over thousands of years of expansion the realm of the Mindless Ones, a races of invincible destroyers, was absorbed.  Unstoppable, the Mindless Ones killed many, including Oinar.

Blamed for the intrusion of the Mindless Ones, the realms sorcerers sought Dormammu and Umar, but the two struck first and bound the sorcerers to silence, and exiled them from the kingdom.  The two then combined their might and sealed the Mindless Ones within a magical prison.  Grateful for stopping the invasion, the citizens of the Dark Dimension appointed Dormammu regent.

Transforming himself into a being of pure mystical energy, Dormammu turned his attention to expanding the realm of the Dark Dimension, attempting many times to annex the dimension of Earth into his own dark realm, where he not only rules as a king but a god, known as the Dread Dormammu.
