The Global War, or the Second World War (Latin: Bellum Mundum) was a global military conflict involving all the existing nations of the world at the time. The conflict was primarily fought between two rival factions : the technologically superior Global Powers, and the numerically superior group formed by most of the remaining world nations, the Allied Coalition. It was the most widespread war in human history, with over 250 million military personnel mobilized by all sides across the world. The resulting devastation led to nearly half of those men dying, along with an additional 180 to 220 million civilians dead from collateral damage. Over 60% of the dead were part of the Allied Coalition, and most of those nations were left absolutely devastated following the war.
