The Eastern Roman Empire, also known as the Greek Empire is an great power in Southern Europe which sprawls across the Eastern Mediterranean Sea. Coming into existence following the 1820 revolution, Greece struggled to get off the ground and to not get reconquered by the Ottoman Empire after its independence. This led to the adoption of Hellenic Militarism, which saw Greece between 1840 and 1900 build one of the largest militaries of the time. They attempted to conquer Constantinople from the Ottomans in 1904, during the Great War, but they were trampled by the Ottoman forces and forced to sue for peace. This was mostly possible because of the Americans, who supported the Ottomans with military aid, economic aid and aid in industrialization.
Finally, in 1956, the Greeks saw their chance, after industrializing and building up their army and economy when the Ottoman sultan committed suicide without an heir. The empire fell into chaos and the Greeks invaded. They took Istanbul, which they renamed to Constantinople, Izmir and even Eskisehir. This attack on a struggling American ally led to the Americans under Leah I to send troops to Anatolia. The fighting was brutal and no side came out victorious at first. That was until the Greeks routed an American force at Konya in 1957, prompting the Americans to pull out of Anatolia, leaving the Turks to their own devices.
The Greeks viewed the Americans as worthy foes and respected their fighting capability and thus never sought to openly provoke them again. The Greeks finally forced a peace treaty among the Turks in which they agreed to annex all territories they had taken, except for Pontus, which would gain autonomy.
The Greek view of Americans was briefly tarnished after the new empress Josephine released private files of Americans systematically committing genocide against Greek prisoners of war and Pontic Greeks. The initial estimates were that the American Army killed between 1.5 and 2.1 million Greeks during the 15 months of fighting between the two. The Americans sent around 100 million dollars per year as reparations though this generally didn't fix things.
Greece obtained Pontus officially in 1982 during the Pontus War, bringing Greece to its highest territorial zenith since the times of the Eastern Roman Empire. However, Greece's last territorial acquisitions came in 1990 when it invaded Italy, embroiled in civil war, and seized Sicily and the south, which was renamed to the Classical Age name of Magna Graecia. The conquests of these lands would prompt Constantinople to declare itself the New Rome, or the re-establishment of the Eastern Roman Empire.
In 2008, the region of Voulgaria demanded greater autonomy from Constantinople. The Greeks refused, and the tension soon exploded into open clashes between the police, later the Greek Army and Voulgarian militia. Finally, international arbitration from Egypt sided with the Voulgarians in 2009, ending the violence, with the Greeks granting them autonomy. 2011 would see the Romanians follow suit, more crackdowns before the Romanians also gained autonomy. Today, Roumanía and Voulgaría are considered Roman vassals and pay annual tribute to Constantinople.
Greece was diplomatically isolated, however. Hostile to the Germans over its influence in the Balkans and conquests of Bosnia and Serbia in the 1990s, as such making them hostile to the Americans, and the collapse of King Constantine's marriage to the American Princess Sophia in 2016 has seen Greece reenvision its foreign policy. In 2018, it formed a pact with the French, who also sought to limit Germanic expansionism in Europe.
