since the second century after Christ, many patria were written in the eastern provinces of the Roman Empire. None of those works was surrendered. Nevertheless, references to this patria in the later tradition of these texts are testimony to the importance of these texts in the Greek speaking provinces of the State. The purpose of this contribution is to analyse the link between the political developments in the late antique and the production of that Patria. I argue that these literary products reflect the change of different cities within the urban hierarchy of the East-Roman Empire. In particular, they testify to the development of urban centres in relation to the three capital cities of the Roman East: Alexandria, Antiochia and Constantinopel. The presence of the eminent courtyard, with resulting supply lines and financial flows from taxes, placed these cities at the centre of extensive urban networks. Peter Brown defined these ürbanised zones, which link the three capitals to their hinterland, using the term “corridors of Empire”. The urban centres that joined these large corridors had to legitimise their new position in the Imperial Network. The best way to do this was to register its own history in the mythic and historical circuits of the Hellenist world. Patria was written for that purpose. Not only did they cast the collective memory of myths, history and traditions of these cities into a fixed model, but they were canonising the acquired status of these cities.
