Karnobat, a town in Bulgaria, has a long history that dates back thousands of years. It has played an important part in the cultural development of the Balkans, serving strategic purposes throughout different historical eras. First recorded by the Arab geographer Al-Idrisi in 1153, Karnobat’s name has changed over time. From the 15th to the 19th centuries, the town was a significant hub for trade, administration, and transportation within the Ottoman Empire, holding an annual fair for a variety of goods. In the Renaissance, Karnobat emerged as a cultural and intellectual centre, furthering the region’s enlightenment through notable events like erecting the “St. John the Theologian” church and founding the Karnobat community. Agriculture, with a focus on wheat and grape cultivation, and sheep farming were key contributors to the town’s economy, while skilled crafts flourished, especially in the late 19th century. Despite encountering challenges during the Russo-Turkish War of 1877-1878, including assaults by Bashibozuks and Circassians, Karnobat persevered. Its liberation was achieved on 24th January 1878 by a Russian detachment. Karnobat’s history illustrates its resilience and its crucial contribution to the cultural and economic development of the region, from ancient times to the modern era of progress and development. Now, Karnobat is a member of the B40 Balkan Cities Network to develop their own city to more cooperate with each other cities which in the network.
