The War of Hum was fought in 1326–1329 between the Banate of Bosnia under Stephen Kotromanić (r. 1322–1353) and the Kingdom of Serbia under Stefan of Dečani (r. 1321–1331).

Branivoje who served King Stefan Milutin (r. 1282–1321) was given the rule of Ston and Pelješac. His family had by 1325 emerged as the strongest in Zahumlje ("Hum"). Probably at their highest point they ruled from Cetina river to the town of Kotor. Though nominal vassals of Serbia, the Branivojević family attacked Serbian interests and other local nobles of Hum, who in 1326 turned against Serbia and the Branivojevići. The Hum nobility approached Stjepan Kotromanić II, the ban of Bosnia, who then entered conflict with Serbia.

In 1326, Ban Stephen II attacked Serbia in a military alliance with the Republic of Ragusa and conquered Zahumlje, gaining access to the Adriatic Sea and including a large Serbian Orthodox Christian population and the Serbian Orthodox Church. This changed the balance of religion in Bosnia, as the Bosnian Bogumils had lost its majority in the realm. He also expanded into Završje, including the Fields of Glamoč, Duvanj and Livanj. The province of Zahumlje was ruled by the Serbian noble family of Branivojević who had tricked Stefan of Dečani's vassalaged Prince, Crep, who was a close friend, so King Stefan had no desire to defend those areas from Ban Stephen's forces.
