The Imperu Restoration of 1868 saw the Imperu (Emperor) [>from Latin Imperator] declare that power be restored to himself instead of submitting to the ruling class Mirita [>from Latin Militia]. Imperu Rūshio led campaigns against the ruling Tasuhaka Miritadom, which ruled since the 1600s, ultimately culminating in the Battle of Borudo, where the Imperial Forces prevailed.

Following the restoration, the new state of Kōrin would be declared with an Imperu as its ruler. Rapid industrialisation and modernisation followed, as Kōrin hoped to catch up with the leading powers of the world, Great Britain, the Roman Empire, the United States and Russia. The previously reigning religion of Kōrin, the Catholic Christian Faith, would be replaced with the Imperial Church, worshipping the Imperu as sons of God, causing strained relations with the Byzantines, the Papal State and Russians.

From the year 1894 onwards, Kōrin sought to expand its dominion outwards and spread the good word of the Imperu. They declared war on the Roman Empire, as Kōrin takes Corsica and Genoa from Roman influence.

In the year 1904, they went to war with Great Britain and Belgium briefly, embarrassing the British Navy by seizing Jersey and Guernsey, as well as Wallonia, which had a majority Kōrishin population.

In 1910, due to strained relations, the Papal-led Italian Confederation was invaded by the Kōrishin Empire, seeing suppression of the Italian language and the Catholic Church and a brutal occupation lasting 35 years. Northern Italy fell firmly under Kōrishin hands while the south was taken over by the Roman Empire.

Kōrin joined the Entente in the First World War extremely late, around 1917, when the Americans also joined. They let Entente troops pass through their territory and defeat the German Empire. Kōrin also joined to secure a foothold in the neutral Roman Empire. They were able to seize Sardinia by the end of the war, with limited casualties.

With the Great Depression halting their hunger for domination and conversion, the Kōrishin military leaders take over the government, once again putting the Imperu in a figurehead position. In 1931, they invaded Southern Italy and Sicily, taking it from the Roman Empire.

This ignited another war in 1937, the Roman-Kōrishin War, lasting from 1937-1945, seeing Kōrin invade Rome's African colonies in Roman Mauretania. Kōrin seized the opportunity of the Roman Civil War (1929-50), as the Empire fell into chaos and warlordism. The invaders were brutish, committing extreme war crimes and subjugating the local populace to lab tests and executions. Kōrin signed the Tripartite Pact with their former enemy, Germany and the Ainu Empire in the east in the late 1930s, sparking the Second World War when Germany invaded Poland. With the war in Mauretania dragging out, Kōrin invaded the Balkan States of Yugoslavia, Bulgaria and Albania in 1942, opening up a new front, as they threatened Constantinople by mid-1942. The Ainu Empire bombs Pearl Harbor in that same year, bringing America into the war. Kōrin forces the Vandal Empire to sign a treaty allowing Kōrishin troops to pass thorough their lands, opening up a new front in Libya and Eastern Mauretania. Kōrin also bombs the Egyptian town of Marsa, fully bringing the British into the war.
