Soleillien–Yamato War

The Soleillien–Yamato War, also referred to as the Tozai War (東西戦争/Tozai Senso), was a territorial conflict between the Kingdom of Soleil and the Empire of Yamatai over the latter's recently-established colony at the end of the Vieillesse peninsula.
== Prelude ==
With the conclusion of the Two Hundred years' War in Fuso, the Empire of Yamatai was eager to stretch its wings and expand further. Expanding eastward onto mainland Marlakcor was considered, but ultimately discarded due to belief that the historically chaotic lands of the east would be too much to handle. Yamato expansionists had long known about land of Aquilonis to the far west across the Tozai Sea thanks to Genjin sailors and explorers. Despite it's distance, most viewed the new and untried lands to the west as a better place to set up and expand. Toki-tenno agreed and gave the edict to start colonization efforts in 2145TR.
The first settles arrived in what was to become Yamatai's colony in 2148TR/432DE, disregarding the fact that the sudden arrival of unfamiliar foreigners would bring the ire of the locals; in particular was the expanding Kingdom of Soleil, whose own people were starting to expand into the region after recently conquering the petty kingdom of Zondal, the last Salrin kingdom in eastern Vieillesse.
== War ==
The war began in 446DE/2162TR/3879PCZ, barely fourteen years after the colony's establishment, when the Kingdom of Soleil, then under the rule of the Puissance dynasty, attacked the colony, viewing the expansion of it as a threat to Soleillien expansion.
== Aftermath ==
The outcome of the war was not favorable for Yamatai, as their ambitions of westward expansion had been thwarted both militarily and by economic burden. It also had the effect of souring relations between the two powers for decades, albeit in different ways: Soleil all but forgot about the conflict for a time – relegating it to merely a footnote in the history books as a successful war of conquest – as the powers that be at the time were more focused on securing their place in Aquilonis; nonetheless they were wary of foreigners from then on. Yamatai, meanwhile, never forgot and retained an antagonistic stance against Soleil from then on.
One other result of the conflict was that it brought black powder and black powder weaponry to Aquilonis for the first time. Some was captured by the Soleilliens during the war but much was left behind when Yamatai vacated the peninsula. Soleil was quick to incorporate it into their ways of war and entertainment, and as people learned to make more from there it spread across Aquilonis and eventually into Soligaia.
A few generations later, all former animosity between the two country's was forgiven and forgotten by both governments and their peoples when Soleil, under the newly inaugurated Sorcellerie dynasty, intervened in Fuso on the side of Yamatai against the invading Lin dynasty of Tianchao in the Lin Invasion of Yamatai.
A sense of camaraderie developed between the two peoples as they fought side-by-side to expel the Lin invasion and free the occupied territories and islands of Yamatai from Lin rule. The success gave birth to the Soleillien–Yamato Alliance, a treaty of friendship, free trade and military alliance that endures to this day.
== Notes & Trivia ==
* At the time the war broke out, Soleil had nowhere near reached its modern territorial extant, many holdout territories and independent petty kingdoms/duchies still remained; hence all the grey within Soleil's modern borders on the map.
* This was the sole adversarial war between Yamatai and Soleil.
