In the 15th century, the Eastern Roman Empire is on its knees to the Ottoman threat. The emperor and his sons decided to immigrate the last remnants of the Empire to the west, to a possible continent existing in the legends of the last Varegues living in Constantinople.
Landing on the new continent around 1445, they founded Neo Konstantinopolis. The following years marked the extension of the exiled kingdom, an aggressive diplomacy towards the natives and a strong alliance was formed with the Viking countries, which would later form Vinland.
A ship that ran aground on the island of Bermuda during the great migration forms a small republic, the Republic of Creta, which Elysia puts under her tutelage, and at the same time, an important personality of the exiled kingdom requests permission to leave by sea, following the coast southwards. In exchange, he offers all the information he can find on the spot, as well as an alliance. This leads to the creation of Lakonia.
After a century, the Patriarch of the capital decided to separate the Church of Elysia from the Orthodox Church of Europe.
At the beginning of the 16th century, the country is big enough, which leads to a reform of the kingdom, in order to turn it into an Empire with a Senate, allowing the important affairs of the country to be settled.
This coincides with the new policy of Creta, which is a colonization of the islands discovered in the south of the continent. The Kykladia Islands then gradually came under the yoke of Elysia, administered by the Duke of Kykladia.
In 1503, Portugal and Elysia signed the Treaty of Lathanopolis, which offers the North of the New World to Elysia and her allies, and the South to Portugal, although it is mainly Spain that will benefit, going a little further north than the treaty forming the Central American States.
Vinland and Elysia will continue their expansions towards the west, forming a border between the two countries that will not move until today. In 1532, Scouts found the first Persian cities, the first event in a long series that led to numerous wars between the two peoples. These Zoroastrian Persians fled following the invasion of their lands by the Muslims.

At the beginning of the 18th century, and until the end of the 19th, Elysia will try to reform a state one Europe, which will be a mixed success taking then the form of the state of Konstantinia, taking globally the Peloponnese and the Attica. This will be extremely stable and will stir up a very strong Roman nationalism.

The Palailogos formed many alliances with European empires, first with the Russians, then France and finally Great Britain in 1899. This allowed the Romanov dysnasty to arrive on the Elysian imperial throne in 1895, with the death of the last of the Palailogos, allowing Nicolaos II to be emperor of Elysia, his brother Mikhail becoming emperor of Russia a year later. Four countries will then form the Entente, in order to counter Germany, Austria, Hungary and the Ottoman Empire. In 1914 war broke out, after the declaration of war by Austria against Serbia. Russia and then the Entente entered the war against the Central Alliance. In 1915 the Shahanshastan joins the Central Alliance in order to take territories in Elysia, Vinland being neutral. This greatly destabilized Elysia, forming a front right in the plains of Shythai. In 1917 the Red Revolution began in Russia, but Germany was famished and the Slavic peoples rebelled against Austria-Hungary. A ceasefire is signed between all the belligerents in 1919.
The Ottoman and Austro-Hungarian empire is dismantled as well as Germany which loses its territories as in our reality. Russia is red, and the borders between Shahanshastan and Elysia are not clear. The empire disintegrates, Lakonia and Kykladia separates peacefully from Elysia, but the Barbaroi of Skythai take up arms against the two great powers of the region forming a great barbaroi state in the centre of the continent of Elysia.
