War of the Weary

"The War of the Weary. That's what they're calling it. If I may ask of you mother, end this war the moment they sue for peace."

- Suna Emperor Brianov Marcellino to his mother

The War of the Weary is a minor war begun by the expanding Setupit Empire as it attempts a conquest of the Russius Empire. Due to the tiring wars of expansion and four bad years the Russius Empire had faced, it is known as the Weary Wars, or War of the Weary, since moral was low and the Setupit Empire relied on deterrence to continue defending the area it had conquered. A short-lasting war, it ended with the Treaty of Riverdale, and despite boiling tensions, the two empires eventually improved relations.

Prelude
The people of Japan had an era of (mostly) peace and constant development after the era of warring clans was ended by Mahertian I. His son, Mahertian II was a militarist and a voyager in his young age. He considered non-Japanese people to be inferior and less developed mentally. He justified his conquest as to "spread the true path of civilization and to share prosperity with other people".

Thus the nation of Japan is transformed to the Setupit Empire, annexing small isles within its reach, and had also to sailed north. It attempted to invade the kingdoms of Baekje and Silla, but failed due to the Chinese Empire providing a vast coastal defense for these kingdoms. The Setupit Empire looked further north, and invaded the weakly defended State of Dalner, of the Russius Empire.

The Russius Empire was still recovering from the Dreadful Years, and its military had been exhausted due to the Suna-Russius Expansions. The annexed state of Dalner had very poor relations with the rest of the Russius Empire, and even rebelled against the emperor. Mahertian II promised the people of Dalner better conditions under his rule, and encouraged them to rally to his side and support his cause.

War
The Setupit empire begun an Invasion of Dunay Bay, with 200 Setupit ships landing more than 22,000 men. They were met with few resistance, and this invasion quickly alarmed the leaders of Russius.
