Constantinople (Κωνσταντινούπολις, Kōnstantinoúpolis), formerly known as Byzantium, is the capital of the Hellenic Empire. One of the largest cities in the world and of Europe, built on both Europe and Asia, it served as the capital of the Eastern Roman Empire (330-395), its successor state the Byzantine Empire (395-1204, 1261-1453), the Latin Empire (1204-1264), the Ottoman Empire (1453-1921) and now the Hellenic Empire (1947-present). It was an independent free city under international supervision from 1921 to 1947.

The conquest of Constantinople was a war goal of Greece in the Great European War (1916-1921) according to the Megali Idea irrendentist thought : helped by the Russian Navy that enabled a blockade of the capital, the European side of the city was under siege from 1917, before a Greek landing in the Dardanelles the following year allowed the Concord to lay siege to the Asian side : Constantinople fell to the Greeks on May, 15 1919, ending more than 450 years of Ottoman domination. Greek victory was almost guaranteed but a counter-attack from Bulgaria and Germany saw the Greeks expelled from Constantinople in 1920 ; the Treaty of Nicosia acknowledged the Ottoman defeat but British pressure existed for Constantinople to become a neutral city in order to insure peaceful trade in the Straits : as such, the status of Free City was created for Constantinople, as a neutral state under international protection. American humanitarian Herbert Hoover become the first Governor-General for a seven-year mandate.
Even if the Marmara Crisis in 1922 saw war almost reignited after Greek troops had crossed the borders of the international area, the Free City was a peaceful place in a very trouble Middle East, providing shelter for Greeks, Turks, Armenians, Levantines and Jews that had always lived in the city : instability in both Greece and Ottoman Turkey allowed a steady flow of refugees and the city to rebuilt itself. The Greek population in the city demonstrated for Enosis (Union with Greece) in 1922 and 1934, but under the various Governor-Generals of the Free City (Hoover, Norwegian Mowinckel, Japanese Konoe, Swiss Cohen), the city focused on inner development and help for trade ; the Venice Convention in 1937 eased the restrictions on international trade in the Straits and cemented the status of the Free City.
The chaos of the World War threw the existence of the Free City in disarray : the British and Germans weren’t available anymore to guarantee the neutrality of the area. The Enver Pascha regime in the Ottoman Empire saw the occasion for a reconquest of the lost territories of the previous war, and invaded Constantinople in 1945 ; the Greeks, with Russian support, responded by a quick counter-attack and the Greeks entered Constantinople a second time, on September, 1 1946. Governor-General Albert Cohen, to prevent further bloodshed, surrendered his powers to Greek authorities. Vowing to “erase the humiliation of 1920 and complete the Megali Idea”, Prime Minister Alexandros Papagos formally declared the Hellenic Empire, during a mass attended by King-turned-Emperor Alexandros in then Hagia Sophia Mosque. The city of Constantine became capital to the new Empire ; the Allies acknowledged the Greek annexation in 1950 as a condition for Hellenic participation to the World War.
The Greeks subjected Constantinople to the same laws of return that they had enacted in Anatolia, giving free rein and help to Greek immigrants to the city ; the state of oppression in the Ottoman Empire, notably during the Arslan Pasha regime (1971-1997) and the Ottoman Civil War (1998-2002) also led to a steady Turkish immigration to the prosperous city, allowing the population to increase fifteenfold during the latter half of the Twentieth Century and to increase its occupation of the Asian side.
The Greeks turned to a “Hellenification” of their new capital : the districts reverted to their Byzantine-era names, while palaces and mosques were turned into administrative buildings and churches : as such, the Dolmabahçe Palace became the Bosphorus Palace, seat to the Hellenic Emperor ; the Ciragan Palace became seat to the Greek Parliament ; and Hagia Sophia Mosque, the greatest achievement of the Byzantine Era, was consecrated back into a Greek Orthodox cathedral in 1955.
This agressive policy led to many tensions with the Turkish population, as the Greeks hadn’t suspected they had inherited a cosmopolitic city : the Hagia Sophia consecration led to massive race riots in 1955, a fixture of Constantinopoulian history, as others occurred in 1968, 1969, 1970 (against the military regime), 1995 (for acknowledgement of Turkish heritage), 2008 (for free islamic education), 2015, 2016 (against anti-Muslim laws). As the capital of the Hellenic Empire, Constantinople was also victim of various terrorist attacks : from the Greek far right in 1977, from the lar left in 1988, from islamists in 1992, 1999, 2003, 2010 and 2017 ; notwithstanding with the Battle of Constantinople during the Sixth Greco-Turkish War (1986-1987) Nevertheless, Constantinople also had periods of peaceful co-existence, mostly after the 1981 Smyrna Agreement, that saw Greek citizenship bestowed upon Turkish-speaking residents : Turkish-born Ilhan Kesici was elected Mayor in 1994, and the city welcomed the Olympic Games in 1996. In Greek politics, heavily globalized Constantinople has been a beacon for Venizilism and progressism, as Mayor Alexi Giannoulias, a descendent of Greek emigrants was elected Mayor in 2018 for PAKK, before splitting from the party to help form the left-wing Lambrakis Lives! party.
