Domanek (Serbian: Доманек; la|Domanec; 1054–55) was a local Slavic chieftain from the region surrounding Trebinje. After a revolt and the murder of earlier ruler of Travunia (ca. 1054–1055), the rebel chieftains made Domanek their leader and a ruler of Travunia.[2]
According to the Chronicle of the Priest of Dioclea, when Stefan Vojislav, the Grand Prince of Duklja, died, the lands were divided between his widow and five sons.[2] [3] Gojislav received the Trebinje region.[3] The local nobles eventually rose up and killed him.[3] The nobles then set up one of their own, Domanek, as prince, in ca. 1054.[2] [3] [1]
Mihailo I, the holder of Duklja (the crownland), and two of his brothers, led an attack into Travunia, capturing the murderers and giving "them a horrible death".[2] [3] Domanek fled the lands, and Saganek, another brother of Mihailo, succeeded as the rightful Prince of Travunia.[3] Domanek returned shortly after Mihailo's departure, and expelled Saganek.[3] Mihailo offered the office to Radoslav, who declined, afraid of losing Luška župa (future Zeta).[2] [3] Radoslav perhaps distrusted his brother, thinking he would seize Zeta, but Mihailo seems to have offered him a deal.[3]
The Byzantine Empire, wanting to take advantage of the death of Stefan Vojislav, prepared an offensive against unstable Duklja.[3] At this time, the four remaining brothers made peace and established an alliance.[3] The treaty concluded is the oldest in Serbian history.[3] After the agreement, Radoslav attacked Trebinje, killing Domanek.[3] Radoslav went on to conquer Zahumlje.[2]
