From Halopedia, the Halo Wiki
The Inner Colony Wars were a series of conflicts that occurred sometime in human history. Assuming that the Inner Colony Wars were a distinct event, they probably occurred in the 25th century as there obviously was no distinction between Inner and Outer colonies before the establishment of the Outer colonies.
Of what is known, "instant, uninformative news reports caused massive civil unrest" and "almost tore down Earth's culture." [1]
