Category:2nd Founding

This category covers all articles relating to those Space Marine Chapters created during the Second Founding, which took place in 021.M31. This 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 newly authored Codex Astartes, written by the Ultramarines' Primarch, Roboute Guilliman.
