Hellenoturkism (Greek: Ελληνοτουρκισμός, romanized: Ellinotourkismós; Turkish: Helenotürkizm) is a political concept that encompasses two things: a fact of civilization (i.e. the co-habitation and interdependence, since the 11th century) of the Greek and Turkish peoples and cultures, and a political ideology based on the above civilizational phenomenon, which aims at establishing a Hellenic-Turkish political ensemble, national, and cultural identity.

Most believers in the ideology support differing main principles and points, although generally supported ideas are that, one, both nations and peoples share similar cultures, traditions, histories, and also a mixed genetic similarity.

And two, that such a unification would create a new global and regional, military and economic power within the European Union and NATO, which would also peacefully resolve ongoing disputes between the Cypriot, Greek, and Turkish states and communities such as the Cyprus problem, the Aegean problems, and also Maritime-border disputes in the Mediterranean between the two Cypriot communities and three nations.

According to Dimitri Kitsikis, from the time of the Persian Empire and Alexander the Great, to the collapse of the Ottoman Empire in the 20th century A.D., the Intermediate Region has been covered by an ecumenical empire that had common civilizational characteristics, despite the fact that it passed into the hands successively of the Persians, to the Greeks, to the Romans, to the Byzantines and, finally, to the Ottomans. This central civilization of the Intermediate Region, existing since the time of Cyrus the Great, bore the characteristics, since the 11th century A.D. and for the last thousand years, of Greek and Turkish cultures. The Ecumenicity of the Empire was Hellenoturkism.^[1]

In the 15th century, a Greek philosopher, George of Trebizond, 1395-1484 (the date of his death varies from 1472 to 1486 depending on the sources), who aimed at synthesizing Islam in the form of Alevism and Christianity in the form of Greek Orthodoxy,^[2] is considered by some supporters of Hellenoturkism as one of the main thinkers and founders of their ideology.^[3] He addressed the new ruler of the Empire, Fatih, or Mehmed the Conqueror, in a letter of 1466 as the legal emperor of the Romans and of the whole earth, and also as the common emperor of both Romans and Turks.^[4]

In the 20th century, the ideology of Hellenoturkism was revived by the historian Dimitri Kitsikis who beginning in 1966, with numerous books, articles and conference papers focussed on the subject, and with political activity in both Greece and Turkey, as an advisor of both Greek President Konstantinos Karamanlis and of Turkish President Turgut Özal, strove to establish the basis of a Turkish-Greek Confederation.^[5]

According to proponents, a bilingual "Greek Turkish Confederation" (East Mediterranean Confederation) between Greece, Turkey and Cyprus (with national capitals in Athens, Ankara and Nicosia, and Confederation parliament in Istanbul) would (to an extent) be a reincarnation of the Byzantine/Ottoman Empires; thus filling the political, cultural and economic vacuum left behind by the absence of these two historic superpowers in the East Mediterranean region. It would have the largest economy and military in the area covering the Balkans, the Middle East, the East Mediterranean, the Caucasus and Central Asia, and could become a key global great power due to its geographic location. During the 2010-2015 Greek financial crisis, the idea resurfaced both in Turkey and Greece.^[6][7]

However today, Hellenoturkism has little support in Turkey or Greece (excluding Cyprus)^{[citation needed]}. Although it has significantly grown in recognition, support and popularity as a result of its presentation in digital media and online platforms or forums.^{[citation needed]}

Meanwhile in the recognized Cyprus and unrecognized North Cyprus; the ideas of a united Cypriot federation, Taksim (Partition between Greece & Turkey) by Turks, and Enosis (Unification with Greece) by Greeks are more common.
