Croatian–Bulgarian battle of 852 was the first known military conflict between the armies of Bulgaria (from 913 Bulgarian Empire), under the rule of Boris I, and the Duchy of Littoral Croatia, ruled by Duke Trpimir I, during the First Croatian-Bulgarian War. It was fought on the Croatian territory in the vicinity of the Croatian–Bulgarian border in present-day northeastern Bosnia and Herzegovina. None of warring sides emerged victorious, Bulgarian forces retreated and finally both parties subsequently concluded a peace treaty.
