Nigbolu, which was known as a “castle city” for centuries, was founded on the shores of the Danube River in the northeast of Bulgaria by Byzantine Emperor Herakleios in 629. As Nigbolu had a great strategic importance, it was occupied by various tribes and nations for many times throughout the history. Nigbolu, which fell under the hegemony of Ottoman Empire as a result of Nigbolu Battle between crusaders and Ottomans in 1396, became an important center of Ottoman Army especially with the support of Ottoman Empire. Furthermore it became a reasonably prosperous and developed city with the constructions of the mosques, madrasas, imarets, inns, Turkish baths, caravanserais, bazaars, fountains as a reflection of Rumelian civilization by the help of wealthy and helpful families and charities. Nigbolu, where the population mostly consists of Turks, became one of the important city of the culture of Rumelian civilization by developing enormously in economical and cultural fields. At the same time, Nigbolu is the city which brought many poets such as Âhî (d. 923 / 1517), Sehâbî, Rızayî, Âhî, Fasîhî (d. 1106/1694), Emânî to the Ottoman poetry.
