Glad was defeated by the Hungarians during the 10th century. The Hungarians sent an army against duke Glad and subdued the population between the Morisio (Mureş) and Temes (Timiş) rivers. When they tried to pass the Timiş river Glad came against them with a great army including Cuman, Bulgarian and Vlach support. On the following day Glad was defeated by the Hungarians. The Hungarian attack against the duke Glad in Banat is dated in 934.
In Banat there are still today villages Gladna and Galad, which probably were named after duke Glad. Town Kladovo near Danube in Serbia was probably also named after duke Glad (the original name of this town could be Gladovo, with meaning "a place that belong to Glad" in the Slavic languages). In the 15th century, near the river Zlatica in Banat, a fortress Galad was built. This fortress gained that name because place where it was founded was named Galad. There was also a record about Glad monastery (Galadmonostra) in 1426.
The origin of the name Glad is likely of Slavic origin, thought meaning of the name is not clear, though in the Balkans there are many places with names similar to name Glad could be found in area, where the earliest Slavic names appeared: Gladnica, Gladnić, Gladnik, Gladojević, Gladović, Gladovići, Glade, Gladov do, Gladova vrtača, Gladov vrh, Gladov krš (all in Republika Srpska), Gladište (in Montenegro), Gladišev Dol (in Metohia).
The Romanian historian Neagu Djuvara suggests that Glad probably was a Bulgarian by origin which could be confirmed by the fact that since the rule of Khan Omurtag (814-831) the governors of the Bulgarian provinces were chosen among the ruler's closest nobles, not from the local population.
