Travunija

Travunija was a South Slavic principality centered on Trebinje, in the region later known as Herzegovina. It passed through several noble families under medieval Serbian rule, including the Vojinović family during the Nemanjić dynasty.

After Nikola Altomanović was defeated in 1373, his lands were divided among neighboring rulers. Trebinje came under the Bosnian crown and was held by the Pavlović and later the Kosača family; Ottoman forces conquered the remaining Kosača lands in 1481.
