The Second Human Civil War (known also as the Great Separatist Movement or the Colonial Rebellion) was an official umbrella term used to refer to a number of simultaneous civil conflicts involving the United Nations.
The Second Human Civil War was estimated to have taken the lives of nearly five million individuals; while grossly "outperformed" in this category as when compared to losses seen in the First Human Civil War or Human-Covenant War (which had respectively amassed death tolls of 23,000,000 and 80,000,000,000+), it was nonetheless an extremely horrific war. Some analysts even credit the United Nations conglomerated force with this lowered number with the advent of more advanced techniques that minimize fatalities among both civilians and its personal assets.
Behind the Scenes
Before the Second Human Civil War was conceptualized, a number of lesser revolts were planned to simultaneously take place.
