[7] His father, Nicolas Kitsikis (1887–1978), rector of the Polytechnic School in Athens, the most famous civil engineer of Greece, was a senator and an MP.

[8] His mother, Beata Kitsikis née Petychakis (Μπεάτα Πετυχάκη), was born in Herakleion, Crete, from a wealthy Cretan family and Greek Italian nobles from Trieste of mixed Roman Catholic and Orthodox origin.

Her father, Emmanuel Petychakis founded a beverage production plant in Cairo, Egypt and her stepfather Aristidis Stergiadis was the High Commissioner of Greece in Smyrna (İzmir) from 1919 to 1922.

During the Greek civil war, at the age of 12, he was sent to a boarding school in Paris, by Octave Merlier,[9] the head of the French Institute in Athens, because his mother had been condemned to death as a communist fighter.

[10] He stayed in France for 23 years with his British wife Anne Hubbard, the daughter of a chief justice, whom he had married in Scotland in 1955,[11] with his first two children, Tatiana and Nicolas.

Since then, he has been living and working in Ottawa as well as in Athens,[14] with his second wife, Ada (Αδαμαντία) Nikolarou, whom he married in 1975, the daughter of a farmer from the historic Byzantine town of Mystras, near Sparta and with whom he has two more children, Dr. Agis Ioannis Kitsikis, Swiss Re Head for Canada and Kranay Kitsikis-De Leonardis.

[15] A devout Orthodox Christian, he came to sympathise with the Turkish religion of Alevi–Bektashism[16] and sought to ally it with Orthodoxy, in order to form a basis for a future political union between Athens and Ankara.

Believing in the collaboration of religious communities, as in the millet system of the Ottoman Empire, he worked closely with Shia Muslims in Iran,[17] Jews in Israel[18] and Hindu vaishnavs in India.

[28] Named after his father, who died in 1978, the "Nikos Kitsikis Library and Archives" resides in the home of family member, the former high commissioner of Smyrna (during the Greek occupation of the city between 1919 and 1922) Aristidis Stergiadis (1861–1949), in Herakleion, Crete.

[29] Kitsikis, since the 1960s, has been the recognised theorist, first in Greece and then in Turkey, of the idea of a Greek-Turkish Confederation, which he has promoted by influencing statesmen, politicians, journalists, artists and thinkers in both countries.

[31] He kept close ties with Prime Ministers Konstantinos Karamanlis senior of Greece and Turgut Özal[32] of Turkey as well as the Chinese leaders Mao Zedong and Deng Xiaoping.

[36] He has been the initiator in France of the branch of the History of International Relations that deals with propaganda and pressure as a government weapon of foreign policy.

[42] He is also a recognised poet, with six collections of poetry published by Pierre Jean Oswald (Paris), Naaman (Québec), Kedros (Κέδρος), Hestia (Ἑστία) and Akritas (Ἀκρίτας).

[48] He is the founder of four concepts setting a novel approach for the history of the Greek-Turkish Area to be understood: a) The "Intermediate Region" (Endiamese Perioche, Ἐνδιάμεση Περιοχή) of civilisation, extending from the Adriatic Sea to the Indus River, between the Euro-American West and the Hindu-Chinese East.

The study raises two concepts: 1) the Greek-Chinese civilisation in a global context and 2) its political expression during the last 2500 years, that is, ecumenical empire as a glorified organisational model.

[55] Since 1996, Kitsikis has written for a Greek language, self-published geopolitical quarterly called Intermediate Region wherein he extensively discusses his Hellenoturkist viewpoints and his nationalistic outlook, describing the aims of the journal as "to give the knowledge that will enable the revolutionary overthrow of the structure of the present provincial little state of Athens and the building up of a national regime".
