Across the continent, there are two great Empires, standing tall at either end of the land, overlooking the entire earth, and beneath the two Empires are countless Kingdoms and Duchies.
No one knows whether the two Empires have any friction.
But one thing can be certain, and that is the friction between Kingdoms is not small.
Additionally, Kingdoms need to develop and expand.
Thus, Kingdom Wars came into being.
Every hundred years, major Kingdoms and Duchies engage in a Kingdom War to secure their own interests and gain more benefits.
The Dressrosa Family rose to prominence thanks to a Kingdom War; during one such conflict, the Dressrosa Family leveraged their merits to suddenly become a Count.
This is also the fastest way for the nobility to advance in rank.
Marquis Reman, that was merely a miracle, almost impossible to replicate by others.
Throughout the Kingdom, from Dukes to Viscounts and Barons, most are born from the Kingdom War.
