As early as the 17th century, the various conflicts with European states, piracy in the Aegean and the increasing rebellions of Christians caused political tensions inside and outside the Ottoman Empire. These tensions forced the Empire to generally pursue a lenient policy towards those non-Muslims who inhabited its territory. Greek Christians were now able to assume offices and high government positions, as well as control the trade of the eastern Mediterranean. Thus, in the 18th century, the great commercial activity and the increase in the production of goods brought the Greeks great economic and social prosperity, which in turn contributed to the intellectual development of the people and the flourishing of art and letters.
Under these circumstances, more and more Greek merchants travelled and settled in the 18th century in major European cities, in Venice, Vienna, Marseilles, Moscow, Leipzig and elsewhere. Thus began the emergence of a new class of Christian Ottoman subjects with considerable geographical mobility and bourgeois characteristics. When they returned to their homeland, they brought with them much of the new ideas, objects and intellectual wealth they brought with them from Europe. Their high standard of living, their cosmopolitan lifestyle and their taste in art and letters are reflected in the luxurious houses they build on their return, in Epirus, Mytilene, Thessaly (in Ampelakia and Pelion) and in the rich mansions of Macedonia in Veria, Kastoria, Kozani and Siatista.
It was precisely during this period that the movement of the Modern Greek Enlightenment developed, aiming at the spiritual regeneration of the people through the transference of the ideas of the enlightened West and with the ultimate goal of the nation’s freedom.
At the same time, the transmission of ideas from the West contributed to the renewal of the art of the Ottoman Greeks, who gradually oriented themselves towards new styles and repertoirs, in an attempt to incorporate elements of European Baroque and Rococo.
Experienced craftsmen and popular painters contributed with their art to the construction of the imposing mansions and their rich interior decoration. Thus, the decoration of the mansions, mainly of the 18th but also of the 19th century, became the principal aspect of post-Byzantine secular painting. Impressive frescoes decorate the walls of mansions in Epirus, Thessaly and Macedonia. The painters of this period spread colors, designs and patterns on large surfaces, drawing many themes from European engravings and etchings and then enriching them with their imagination, inspiration and mastery, making them unique. Landscapes, representations of cities (mainly Constantinople), but also mythological and historical themes find their place on the walls of the mansions.
