The Modern Greek Enlightenment (Greek: Διαφωτισμός, Diafotismos, "enlightenment," "illumination") was the Greek expression of the Age of Enlightenment.
The Greek Enlightenment was given impetus by the Greek predominance in trade and education in the Ottoman Empire. Greek merchants financed a large number of young Greeks to study in universities in Italy and the German states. There they were introduced to the ideas of the Enlightenment and the French Revolution. It was the wealth of the extensive Greek merchant class that provided the material basis for the intellectual revival that was the prominent feature of Greek life in the half century and more leading to 1821. It was not by chance that on the eve of the Greek War of Independence the most important centres of Greek learning, schools-cum-universities, were situated in Ioannina, Chios, Smyrna (Izmir) and Ayvalik, all major centres of Greek commerce.
The Phanariotes were a small caste of Greek families who took their collective name from the Phanar quarter of Constantinople where the Ecumenical Patriarchate is still housed. They held various administrative posts within the Ottoman Empire, the most important of which were those of hospodar, or prince, of the Danubian principalities of Moldavia and Wallachia. Most hospodars acted as patrons of Greek culture, education, and printing. These academies attracted teachers and pupils from throughout the Orthodox commonwealth, and there was some contact with intellectual trends in Habsburg central Europe. For the most part they supported the Ottoman system of government, too much to play a significant part in the emergence of the Greek national movement; however, their support of learning produced many highly educated Greek scholars who benefited from the cosmopolitan environment the Phanariotes cultivated in their principalities.
