The European War, considered part of the Total War, splintered the European Union until Chancellor Dominic Cylis brought it to an end.
The European War, with its accompanying destruction, ultimately led to the restructuring of the European Union.
The countries of the European Union had existed in peace with one another for many years. Over time, however, dissent grew between them and led to outright war. Additionally, the Tipping Point--the point at which weather had warmed so much that many areas were rendered unfit for habitation--caused a struggle over resources such as food and water.
The European War devastated Europe, reducing many of its great cities to rubble. While national armies caused much of the damage, local militias also became involved. Uncontrolled by any central authority, at times they were responsible for the massacre of unarmed civilians. Other damage was environmental: the European landscape was badly scarred by the war, making many areas uninhabitable. Chancellor Dominic Cylis finally managed to bring about an end to the conflict. He joined the armies of multiple countries and convinced the army of each that he was capable of leading Europe. Returning at last to his native Greece, he rose through the ranks, assumed leadership of the country, and managed to secure peace in Europe by virtue of his personal popularity.
Following the devastation caused by the Tipping Point and the following war, Europeans had to develop new methods of planting and harvesting food. Raising animals for meat became impractical, and Europeans turned to insects for their protein.
Cylis used the war as a reason to centralize the European Union. Erasing what once were national boundaries, he introduced the Mark as a requirement for citizenship in the changed E.U.
