Hum between the Nemanjic and Subic families at the beginning of the 14th century

Building on the recent results of Serbian and Croatian historiography and the reinterpretation of some data from primary historical sources, the paper examines the issue of the conflict between the Serbian ruling house, the Nemanjic dynasty, and the Croatian magnate family of Subic Bribirski in the region of Hum (Zachlumia, Humska zemlja) in the first twenty years of the 14th century. The paper reviews the conclusions of historians who dealt with this issue in more detail, highlighting the fact that, due to the scarcity and typology of the sources, only two reliable conclusions can be drawn: 1) from the beginning of the conflict until the collapse of the regional domain of Mladen II Subic in 1322, neither side completely withdrew from Hum, and 2) knez Konstantin (comes Constantinus), who governed Hum on behalf of the Subic family (ca. 1304-1307), was not the son of knez Izan Nelipcic, as some historians believed, but a member of the older generation of the Nelipcic family who bore the same name.
