Stephen defeats Kean, Duke of the Bulgarians and SlavsTransylvania, Romania
The Illuminated Chronicle narrates that Stephen "led his army against Kean, Duke of the Bulgarians and Slavs whose lands are by their natural position most strongly fortified" following the occupation of Gyula's country. According to a number of historians, including Zoltán Lenkey and Gábor Thoroczkay, Kean was the head of a small state located in the southern parts of Transylvania and Stephen occupied his country around 1003. Other historians, including Györffy, say that the chronicle's report preserved the memory of Stephen's campaign against Bulgaria in the late 1010s.
