The Outer Colonies are the human-colonized planets farthest from the Inner colonies such as Earth and Reach, with colonies founded after. Until the Human-Covenant war, disorder and rebellion were commonplace. By 2531, the majority of the Outer Colonies had been glassed by the Covenant.[1]

Human-Covenant war Edit


Harvest post glassing.

The Covenant had found Harvest in 2525. After making a disastrous first contact, another battle and a protracted five year campaign began on the planet. However, at that point, the Covenant's genocidal judgement of humanity had spread to many of the other colonies like Circinius IV and Green Hills. In 2535, after ten years of war, most of the Outer Colonies had been lost, with Jericho VII being among the last major ones to fall.

By 2552, though some Outer Colonies still remained in UNSC hands (mostly remote outposts), most were small and rather insignificant worlds. The few significant colonies still under UNSC control lived in constant fear of Covenant invasion. Some of the remaining colonies were bases for outlaws.

Post-War Edit

By the time the Human-Covenant war ended on March 3, 2553, tensions in the remaining worlds had presumably died down enough for the UEG.

The escalated riots in the outer colonies.

In 2558, after the revelation that John-117 had attacked a peace delegation on Biko, huge parts of the outer colonies had again started to distrust the UEG. Many turned to the New Colonial Alliance instead.[2]
