Mongol invasion of Bulgaria and Serbia
During the
.Initially, the troops of Kadan moved south along the Adriatic Sea into Serbian territory. Then, turning east, it crossed the centre of the country—plundering as it went—and entered Bulgaria, where it was joined by the rest of the army under Batu. The campaigning in Bulgaria probably happened mainly in the north, where archaeology yields evidence of destruction from this period. The Mongols did, however, cross Bulgaria to attack the Latin Empire to its south before withdrawing completely. Bulgaria was forced to pay tribute to the Mongols, and this continued thereafter.
Background
Relations between Hungary and Serbia were poor on the eve of the Mongol invasion. The Serbian king,
One of the reasons for the Mongol invasion of Hungary was that Béla IV had given shelter to the Cumans when they fled the Mongol conquest of their land in 1239. After the Cuman leader,
The decision by the Mongols to attack Bulgaria with all their forces may have had the same motive as the initial attack on Hungary: to punish the Bulgarians for giving aid to the Mongols' enemies.[4][7]
Bulgaria in 1242 encompassed the area north of the
In dealing with the Mongol invasions, writers also had to distinguish between Bulgaria on the Danube and the distant Bulgaria on the Volga, which they called, respectively, "Little (or Lesser) Bulgaria" (Bulgaria minor) and "Great (or Greater) Bulgaria" (Bulgaria maior or magna Bulgaria).[9][10][11]
Serbia
When the Mongol commander Kadan withdrew from the invasion of Hungary, he entered Bosnia in late March or early April 1242. Although nominally under Hungarian suzerainty, part of Bosnia had been occupied by Hungarian crusaders opposed to the Bosnian Church while the remainder was under the control of Ban Matej Ninoslav. The passing-through of the Mongols forced the Hungarians to evacuate the territory and allowed Ninoslav to resume control of the whole of Bosnia.[12][13][14]
Continuing south, the Mongols entered the Serbian region of
According to Thomas of Split, a contemporary and partial eyewitness, the Mongols "overran all of Serbia and came to Bulgaria" (totam Serviam percurrentes in Bulgariam devenerunt). Another contemporary, the archdeacon
In the 1250s, William of Rubruck, a Flemish missionary in the Mongol Empire, reported that a French goldsmith, Guillaume Boucher, in the Mongol capital of Karakorum had been captured in Belegrave by the forces of Bujek, a son of Tolui (and not by Kadan). This location is usually identified with Belgrade. If so, then Belgrade, which been under Hungarian control since 1235, was probably occupied by the Mongols in 1241 or 1242. If the former date is correct, it is likely that the Mongols crossed the Danube at Kovin, an important crossing, where evidence of destruction from that period has been unearthed.[17] A large coin hoard buried in 1241 has been found at the nearby fortress of Dupljaja.[18] If the Mongols under Bujek did not take Belgrade while crossing into Croatia in 1241, it is possible that Kadan took it—the Hungarians having evacuated—in 1242 while devastating Serbia.[17]
Although Stefan Vladislav was overthrown by his nobles in 1243, nothing suggests that this was related to his response to the Mongol invasion.
