The Great Wars are a series of wars between the LUEnited Nations and the New Pacific Order, and their respective allies. In particular, the Great War was fought between the CoaLUEtion and the Coalition of Justice, the Second Great War was fought between the League and the Initiative (also referred to as the Farklands War), and the Third Great War was fought between the Initiative and their allies versus the coalition of alliances known as Aegis.
The term Great War has also been applied to three other large-scale conflicts, namely the Unjust War between the Unjust Highway (led by the Unjust Path) and the ~ coalition (led by BLEU), often referred to as Great War IV; the War of the Coalition between BLEU and the Continuum, sometimes referred to as Great War V; and the Karma War, fought by the Hegemony and Karma, which has been referred to as Great War IV or Great War VI, and less often as Great War V.
The rapid expansion of the Second Unjust War has also led it to be called a Great War by a minority of people.
