His son, Stephen III., captured the town of Vidin or Bdin from the Bulgarians, and the district of Syrmia between the Save and the Danube. His brother, Ladislas, who succeeded him, abandoned Vidin on marrying the Bulgarian Tsar’s daughter. A third brother, Stephen IV. the Great, succeeded in 1237. With Stephen Uro§ II. Milutin (succeeded 1275) Servia is almost at the height of her power. He conquered a large part of Macedonia, capturing the town of Serres, besieged Salonica in 1285, and invaded Albania. He added Bosnia, which had been under Hungarian vassalage, once more to Servia, by divorcing his first wife and marrying Elizabeth, the daughter of the King of Hungary, who gave him Bosnia as a dowry.

He conquered the rest of Macedonia and Albania, and reduced Bulgaria to a state of vassalage.

The first Banus, whose name is recorded in authentic documents, is Bori6, who reigned from 1154 to 1163.
