The First Founding of the Space Marine Legions, also originally called the Legiones Astartes, occurred in the late 30th Millennium after the end of the Age of Strife and the Unification Wars that founded the Imperium of Man on Terra. Twenty Space Marine Legions were created from the gene-seed of the 20 Primarchs engineered by the Emperor of Mankind from His own genetic code in His gene-laboratories in the Imperial Palace on Terra beneath the Himalazian (Himalayan) Mountains.
In spite of the fact that the Primarchs were separated from the Emperor of Mankind through the mysterious actions of the Ruinous Powers of Chaos and scattered through the Warp across the galaxy, He managed to keep a small sample of each Primarch's gene-seed, and used this genetic material to create the first Space Marines by further genetically enhancing His own elite, Terran-born soldiers.
With each Primarch the Emperor re-discovered during the Great Crusade, He gave command of the Space Marine Legion created from their genetic material back to them. Each Primarch then set up their Legion's headquarters on his homeworld, from which they also recruited new Space Marines into the Legion. Two other Legions, the IInd Legion and the XIth Legion and their Primarchs, were created by the Emperor, but nothing is known of what became of these Legions and their Primarchs and all data pertaining to them has been deleted from current Imperial records.
