BattleTech eras(Redirected from Civil War era)
Catalyst Game Labs, the current owners of BattleTech, have divided history into six eras. The products they released are grouped in this manner. Recently newer products have included other distinct time periods by splitting the eras into sub-eras which brings the classification up to nine eras. In addition to those, four more distinct non-canon ones can be identified:
|Pre-Spaceflight||Before 1950||Earliest era referenced, when humanity only resides on its planet of origin, Terra.|
|Early Spaceflight||1950 – 2005||Early solar system restricted spaceflight.|
|Age of War||Age of War (First Exodus)||2005 – 2242||The time of the Western Alliance, early Terran Alliance, and earliest interstellar colonies. The Outer Reaches Rebellion resulted in the Demarcation Declaration, the forced independence for most colonies.|
|Age of War||Age of War (Second Exodus)||2242 – 2398||Colonists on marginal worlds resettle or perish. The Terran Alliance collapses; the beginnings of the Terran Hegemony and the Great Houses of the Inner Sphere.|
|Age of War||Age of War||2398 – 2570||The time of the Terran Hegemony and "civilized" warfare between the Inner Sphere houses. The first BattleMech is created.|
