The Third War of Alrussian Aggression
The Third War of Alrussian Aggression was a bloody one, that was until the invasion of The Revolutionary Directorate of Friebruck (Nation) and the initiation of The Friebruckian Invasion of The Three Kingdom's. Initially expecting the weakened Ilmarian Imperium (Nation) to fold against the two pronged invasion of their south region, The Alrussian Federation (Nation) was eventually invaded too, ending hostilities of the Third War in The Treaty of the Two Defendants.
The Third war did not end until a year into The Friebruckian Invasion of The Three Kingdom's as the Imperium was invaded during the war, only for Alrussia to be invaded a year later and a temporary armistice was brokered that eventually turned to a full peace treaty.
