History
The valley below the Balkan range was a heartland of the Thracian Odrysian kingdom. In the late 4th century BC King Seuthes III founded Seuthopolis near Kazanlak, and his people buried their rulers in the burial mounds that dot the valley; the town now lies under the Koprinka reservoir, and a bronze head of Seuthes was found in the Golyama Kosmatka mound in 2004. The painted Kazanlak tomb was discovered by soldiers digging a trench in 1944. Further east, Kabile near Yambol was a Thracian town and later a Roman garrison.
Rome built Augusta Traiana on the site of Stara Zagora, whose history as a settlement goes back to Neolithic villages of around 6000 BC. Under the Ottomans, the Kazanlak valley became a centre for growing the Damask rose and distilling its oil. Sliven and Kotel were strongholds of haiduks, the rebels of the Balkan range, and the Revival produced leaders such as Georgi Rakovski of Kotel and Hadzhi Dimitar of Sliven. In the 1830s Dobri Zhelyazkov opened a textile factory in Sliven, the first in Bulgaria.
In the Russo-Turkish war of 1877, Stara Zagora was burned, and the battles for the Shipka Pass were fought above Kazanlak. Rebuilt on a grid plan, Stara Zagora grew into a regional capital; under communism the Maritsa Iztok coal and power complex was developed on the plain, and the Buzludzha monument was built for the Communist Party in 1981.
