Serbophilia

Overseas Serbophilia (Serbian: Србофилија, romanized: Srbofilija, literally love for Serbia and Serbs) is the admiration, appreciation or emulation of non-Serbian person who expresses a strong interest, positive predisposition or appreciation for the Serbian people, Serbia, Republika Srpska, Serbian language, culture or history.

Its opposite is Serbophobia.

During World War I, Serbophilia was present in western countries.

[1] Political scientist Sabrina P. Ramet writes that Serbophilia in France during the 1990s was "traditional", partly as a response to the closeness between Germany and Croatia.

Business ties continued during the war and fostered a desire for economic normalization.
