The Byzantine–Bulgarian war of 894–896 (Bulgarian: Българо–византийска война от 894–896), also called the Trade war (Bulgarian: Търговската война), was fought between the Bulgarian Empire and the Byzantine Empire as a result of the decision of the Byzantine emperor Leo VI to move the Bulgarian market from Constantinople to Thessaloniki which would greatly increase the expenses of the Bulgarian merchants.
Following the defeat of the Byzantine army in the initial stages of the war in 894 Leo VI sought aid from the Magyars who at the time inhabited the steppes to the north-east of Bulgaria. Aided by the Byzantine navy, in 895 the Magyars invaded Dobrudzha and defeated the Bulgarian troops. Simeon I called for truce and deliberately protracted the negotiations with the Byzantines until securing the assistance of the Pechenegs. Cornered between the Bulgarians and the Pechanegs, the Magyars suffered a crushing defeat at the hands of the Bulgarian army and had to migrate westwards, settling in Pannonia.
With the Magyar threat eliminated, Simeon led his hosts south and routed the Byzantine army in the battle of Boulgarophygon in the summer of 896, which forced Byzantium to agree to the Bulgarian terms. The war ended with a peace treaty which restored the Bulgarian market in Constantinople and confirmed Bulgarian domination in the Balkans. The Byzantine Empire was obliged to pay Bulgaria an annual tribute in exchange for the return of captured Byzantine soldiers and civilians. Under the treaty, the Byzantines also ceded an area between the Black Sea and the Strandzha mountains to Bulgaria. Despite several violations, the treaty formally lasted until Leo VI's death in 912.
