Hum
Hum was a medieval South Slavic principality in the lands later known as Herzegovina and southern Dalmatia. Its rulers at times held independent or semi-independent power, while Serbia, Hungary and Bosnia all exercised authority over the region.
In 1435 the Bosnian noble Stjepan Vukčić Kosača inherited the lordship of Hum from his uncle Sandalj. Stjepan's title of herceg gave rise to the name Herzegovina; Ottoman forces conquered the remaining lands of his successors in 1481.
