2170


 * The Callisto Treaty is signed. The Frieden and Koslovics surrender to the UNSC, officially ending the Interplanetary War.


 * A Unified Earth Government is formed in the wake of the conflicts of the 2160s. Now, the victors were forced to deal with a less obvious but equally serious threat: overpopulation and a massive military that had no enemy to fight. In the post-war period there were massive population surges and the overpopulation, coupled with the destruction and famine bred by the Rain Forest Wars, threatened to destabilize the economy.
