Baghesh was one of the most important cities of the Kingdom of Armenia's province of Aghdznik', and it served as the primary fortress of the province's canton of Salnodzor. Some medieval Armenian writers, such as Anania Shirakatsi and Vardan Areveltsi, later mention it as a part of the canton of Bznunik'. The fortress guarded the Baghesh Pass, which linked the southern reaches of the Armenian Plateau to northern Mesopotamia. The Arabs conquered Baghesh at the end of the seventh century and it eventually became the capital of the Zurārid emirs of Arzan. Because it was on an important trade route, it prospered greatly.
