Trinity Crisis

The Trinity Crisis, otherwise known as the National Guard crisis and the Republic-Trinity war, was a conflict between the Third Republic and the Trinity Empire, sparked by unknown reasons. This crisis lead to the militarization of early Fourth Republic society and the rise of true democracy in the republic, as well as the end of the Third Republic by Cosmical's Betrayal.
Amullia was also a belligerent in the Trinity Crisis, but following the end of the Third Republic, a functional peace agreement was settled between the two regimes, and peace returned.
