First Unification War of Hoterallia

The First Unification War of Hoterallia (ほてらじあの最初の統一戦争, Hoterajia no saisho no Tōitsu Sensō) is a war period in Hoterallia history of near-constant civil war, social upheaval, and political intrigue from 1377 to 1578.

The Battle of Kaiguchiha was the climactic clash between Mamachi's army and the Ji-ji Ho.

The Unification War was initiated by the death of the former Taichima, Hosu Kaiga, with the fact he had no successors, his whole cabinet fell into chaos with multiple warlords fighting to be the next ruler of Hoterallia, which led to collapse the feudal system of Hoterallia under the Hosu Taichimate. Various warlords and clans fought for control over Hoterallia in the power vacuum, while a small yet relentless warlord clan known as the Ji-ji Ho Clan which fought for unified Hoterallia, runs by fear and paranoia. They adopted multiple war tactics that is popular in Hoterallian such as the use of multiple rifle lines, war charges and harsh guerilla warfare. Mamachi Konshu dissolved the Hosu Taichimate in 1465 and launched a war of political unification by force, with one of the most notable and brutal campaign known as Seibu-sensō War, also known as the Western War. Mamachi's successor Konkiu Hejiro completed his campaign to unify Western Hoterallia and face off with the new and strengthen, the Shiro Dynasty, the Emperor of the Shiro clan at the time was Washita, he launched a massive unification effort using diplomacy and sometimes war to unified Eastern Hoterallia under his control. The two faction fought before multiple times with the Shiro topping the Taichimate using the sheer force of numbers and new war tactics, in 1566, the two finally fought each other after accumulating and assimilating smaller warlords in their area. The war was one of the most brutal during its time, with hundreds of thousands dying on both sides, but at the end, using espionage and careful planning, the Shiro Dynasty's army kill Konkiu and crippling the whole Taichimate, which in turn, helped the Shiro to fully push and unified Hoterallia.

The Koi-kuo period was named by Hoterallian historians after the otherwise unrelated but similar second Warring States period of Hoterallia in 1949. Modern Hoterallia recognizes Mamachi, Konkiu, and Washita as the three "Great Unifiers" for their restoration of both the east and west region of the country.
