Zagore (Bulgarian: Загоре [zɐˈɡɔrɛ]), also Zagorie (Загорие), Zagora (Загора), or Zagoriya (Загория), was a vaguely defined medieval region in what is now Bulgaria.
Its name is of Slavic origin and means "beyond [i.e. south of] the [Balkan] mountains".
The region was first mentioned as Ζαγόρια in Greek (in an Old Bulgarian translation it was rendered as Загорїа) when it was ceded to the First Bulgarian Empire by the Byzantine Empire during the rule of Tervel of Bulgaria in the very beginning of the 8th century (Byzantine–Bulgarian Treaty of 716).
[2] During the Second Bulgarian Empire, the region was also mentioned in Tsar Ivan Asen II of Bulgaria's post-1230 Dubrovnik Charter, which allowed Ragusan merchants to trade in the Bulgarian lands, among which "the whole Zagore" (пѡ всемѹ Загѡриѹ).
[4] Similarly, later Ragusan sources regularly evidence the active import of high-quality Zagoran wax (cera zagora, variously spelled zachori, zaura, zachorj, zacora) from Bulgaria, often bought in Sofia.
