Inner Colony Wars (Stormverse)

The Inner Colony Wars comprised a period of civil disorder and conflict throughout recently established Human colonies, starting in 2386 and ending in 2411. The Inner Colony Wars go by serval names, including "the Inner Colonies Emergency," "the Colonial Wars" and later "the First Colonial War," and "the interstellar calamity." Localized civil disorder occurred on several colony worlds, arising from everything from perceived government negligence or abuse, to insufficient reaction to droughts and environmental hazards. These protests turned violent and some individuals and organizations took advantage to press for greater autonomy for some colonies and corporate control for others. While the Colonial Military Administration initially left the issue to be dealt with by local governments, it quickly became clear that they were incapable of managing these crises. 
The CMA lacked the manpower to intervene in colonial affairs, but the United Nations Space Command did not. As the political repercussions of colonial difficulties roiled the already-tense Sol System, the UNSC deployed tens of thousands of marines and soldiers to unstable colonies to restore order. These deployments steadily increased from tens of thousands to hundreds of thousands, and eventually to millions. 
It was at this time that Reach became a major staging area for these deployments, and the UNSC began to establish a more permanent position on the planet, much to the chagrin of the CMA. The period of significant instability calmed by 2411, with the UNSC presence amongst the 210 first-wave colonies well-established. For its part, the CMA was determined to reestablish itself with newer colonies, soon to be known as the Outer Colonies. CMA forces continue to operate in the Inner Colonies, but the overall focus of the organization shifted outwards.
