The Book of Dede Korkut is an early record of oral Turkic folktales in Anatolia, and as such, one of the mythic charters of Turkish nationalist ideology. The oldest versions of the Book of Dede Korkut consist of two manuscripts copied sometime during the 16th century. The twelve stories that are recorded in these manuscripts are believed to be derived from a cycle of stories and songs circulating among Turkic peoples living in northeastern Anatolia and northwestern Azerbaijan.
According to Lewis (1974), an older substratum of these oral traditions dates to conflicts between the ancient Oghuz and their Turkish rivals in Central Asia (the
Pecheneks and the Kipchaks), but this substratum has been clothed in references to the 14th-century campaigns of the Akkoyunlu Confederation of Turkic tribes
against the Georgians, the Abkhaz, and the Greeks in Trebizond. Such stories and songs would have emerged no earlier than the beginning of the 13th century, andthe written versions that have reached us would have been composed no later than
the beginning of the 15th century. By this time, the Turkic peoples in question had been in touch with Islamic civilization for seeral centuries, had come to call
themselves "Turcoman" rather than "Oghuz," had close associations with sedentary and urbanized societies, and were participating in Islamized regimes that included
nomads, farmers, and townsmen. Some had abandoned their nomadic way of life altogether.
