The paper focuses on the visit of the King of Serbia to Bulgaria on October 1904, as a part of diplomatic relations between the two Balkan states in а very complicated international situation due to the Russo‐Japanese War that began that year. In 1904, Serbia and Bulgaria had a reason to feel threatened by both the dynamically changing situation in Europe and the world and their national problems. This year is very important for the Serbian‐Bulgarian relations and has its results mainly in the bilateral intensification of the dialogue in diplomatic, economic, cultural and social spheres.
