Category:Second Founding

The Second Founding of the Space Marines occurred seven standard years after the end of the Horus Heresy, in the early 31st Millennium.

This Founding involved the division of the existing Loyalist Space Marine Legions into the far smaller, 1,000-man autonomous Chapters of the Space Marines as decreed by the new Codex Astartes, written by the Ultramarines' primarch, Roboute Guilliman.

The remaining Loyalist Space Marine Legions were divided into smaller Successor Chapters -- one Chapter maintained their parent Legion's original name, badge and colours, while the remaining Chapters took new names and heraldry.
