Two perspectives were taken into consideration: the time and the essential contribution of the Greek immigrants to this place, especially after 1829, when Wallachia (Ţara Românească) was opening up its old Danube port of Brăila towards the European commerce. This way Brăila was leading the greater region of Wallachia - just like Galaţi was leading the greater region of Moldavia - to the market economy. Our book is a modest homage to those who not only greatly contributed to the ancient European culture and civilisation, but to the modern European spirit as well. The publishing of the present studies is filling a gap in this field and the texts not only constitute one of our old research preoccupations, but meet the expectations of the Hellenic Union of Romania which has a strong Community in the city of Brăila. Firstly, the study of the links between the Romanians' ancestors and the ancestors of the Greeks living today in Brăila region and secondly, a clarification of the links between the Byzantines and Romanians are both essential for the understanding of the phenomenon that (after the Adrianopol Peace Treaty - 1829 and the application of the Organic Rules) triggered the coming into being of the largest and most important Neo-Hellenic Community of all the territory of Romania, in Brăila.
