October, 2010. "The Ketāb-e Dede Qorqut, which is a collection of twelve stories reflecting the oral traditions of the Turkmens in the 15th-century eastern Anatolia, is also called Oḡuz-nāma" It is a collection of twelve stories reflecting the oral tradition of Oghuz nomads. Since the author is buttering up both the Aq Qoyunlu and Ottoman rulers, it has been suggested that the composition belongs to someone living between the Aq Qoyunlu and Ottoman Empire. Geoffery Lewis believes an older substratum of these oral traditions dates to conflicts between the ancient Oghuz and their Turkish rivals in Central Asia (the Pechenegs and the Kipchaks), however this substratum has been clothed in references to the 14th-century campaigns of the Aq Qoyunlu Confederation of Turkic tribes against the Georgians, the Abkhaz, and the Greeks in Trabzon.

In the span of the 17th century and 18th century, Fizuli's unique genres as well Ashik poetry were taken up by prominent poets and writers such as Qovsi of Tabriz, Shah Abbas Sani, Agha Mesih Shirvani, Nishat, Molla Vali Vidadi, Molla Panah Vagif, Amani, Zafar and others. Along with Anatolian Turks, Turkmens and Uzbeks, Azerbaijanis also celebrate the epic of Koroglu (from for blind man's son), a legendary hero or a noble bandit of the Robin Hood type. Several documented versions of Koroglu epic remain at the Institute for Manuscripts of the National Academy of Sciences of Azerbaijan.
