Bulgaria's unification with Eastern Rumelia on 18 September 1885 upset the regional balance of power. Serbia, seeking territorial compensation and fearing a stronger Bulgaria on its eastern border, initiated hostilities. Austria-Hungary's influence over Serbia and concern about Balkan stability further shaped the diplomatic environment preceding the conflict.
The Kingdom of Serbia declared war and invaded the Principality of Bulgaria on 14 November 1885. Despite Bulgaria being a nominal Ottoman vassal, the Ottomans did not intervene. Bulgarian forces repelled the Serbian invasion and counter-invaded Serbian territory. The fighting lasted only two weeks before Austria-Hungary pressured Bulgaria to halt its advance, leading to a truce on 28 November 1885.
The Peace of Bucharest, signed on 3 March 1886, restored the pre-war boundaries without territorial changes for either side. More significantly, the war's outcome compelled the European great powers to acknowledge Bulgaria's unification with Eastern Rumelia, consolidating the Bulgarian state and reshaping the balance of power in the Balkan Peninsula.
