The Rusian letopises are a primary source of information about the diplomatic practices of the Rurikids. These accounts have been analysed regarding politics, culture or rituals. In contrast, attention has rarely been paid to the role of the space in which the international non-military events described by the Rusian bookmen took place. I would like to analyse the fragments of the three most important monuments of South-Rusian historiography dating from the end of the 10th to the turn of the 13th/14th centuries. I have in mind the Primary chronicle, the Kyivian annals and the Chronicle of Halych-Volhynia. These contain a number of very interesting references to the international gatherings that took place in border areas where the spheres of influence of two states met. Based on some selected examples, I will present why and on what basis the specific borderland space (border settlements, certain rivers, etc.) regularly became a place where international politics was conducted.
