Summary/Abstract: Serbian war allies Britons had a decisive role in the creation of the borders of the Banovina Hrvatska in August 1939, but also, in all probability, in the creation of the post-Yugoslav borders during 1990’s, which, by the will of Western liberal democracies became state borders. Great Britain tried to influence as much as it was possible the formation of the inner administrative borders, which were since their creation in 1945/1946 were federative, with the confederal tendencies. We don have documentary sources, but it could be assumed by analogy,that apart from the Soviet influence, Western liberal democracies centred around London and Washington, decided about the border lines.
