Serbia declares war on Bulgaria over 1885 Unification move
The Serbian King Milan declared war on Bulgaria on November 14, 1885, following the Unification of Eastern Rumelia and the Principality of Bulgaria. This act altered the Balkan balance of power, provoking negative reactions from neighboring states and European powers. Serbia sought territorial compensation, while Russia demonstrated its disapproval by recalling its military officers from Bulgaria, leaving the Bulgarian army without its senior command staff.
Despite this disadvantage, the Bulgarian army repelled the Serbian invasion and launched a successful counteroffensive. The conflict concluded with the Bulgarian forces ceasing their advance into Serbia. The subsequent peace treaty, signed in Bucharest in February 1886, reaffirmed the pre-war borders.
The war resulted in several hundred casualties on both sides and over eight thousand wounded. Crucially, the military outcome led to the international recognition of the Unification, which had originally sparked the hostilities.
