The beginning of the 19th century is characterized by increasing national movements on the territory of the Ottoman Empire. It is a situation used by the major powers, especially by the Russian Empire that supported the Greek ethnicity in its national aspirations both economically and politically. As an example it can serve the support of the numerous secret societies which had the aim to destabilize the situation in the Ottoman Empire. One of these organizations is “Filiki Eteria” founded in 1814 in Odessa. The beginning of the Greek revolution in 1821 and the position of the major powers determined the Russian authorities to carry out some changes to the Statute of the Greek minority and the policy towards them. As a result the Russian administration took the following measures: stricter monitoring of the border with the Ottoman Empire; the registering of all migrants, being listed the participants in the Eteria revolution, who would be disarmed and some of them would be arrested. The new refugees were to be involved in the Russian society. As a consequence it was settled: • Greek refugees were to be registered and divided according to the social principle, occupation and trade. • the Government was to employ them. • these refugees were to pass in small groups the Russian territory. • to select Greek sailors and grant them some jobs in the Russian ports.In order not to lose the Balkan peoples’ respect, the Russian Government decided to grant financial assistance to the new arrivals. But in the documentary sources we notice that the redistribution of the material aid was not uniform, but taking into account the beneficiary’s specialty and social status. This attitude was spread on the Greek ethnicity, being discriminated all those who have been registered as Eteria members. As an attitude towards the participants to Eteria this policy continued until the year 1829. Signing the peace Treaty at Adrianople and changing Russia’s political vector determined the Russian authorities to change their attitude towards the Eteria members, offering them the right to leave Russia. This is a context which would start a new page in the GreekRussian relationship. In conclusion we can say that the policy of the Russian authorities towards the Greek community was determined by the geopolitical situation of that period and, what was especially obvious in Russia’s interests, to strengthen its position in the Balkans to the prejudice of the Ottoman Porte. In this context the Greek Diaspora in Russia tried to take advantage of the new juncture setting its interests above those of the Tsarist Empire. Their efforts have been completed successfully with the signing of the Peace Treaty at Adrianople in 1829 that put the basis of the national Greek State.
