Carpet (''halı'') and tapestry (''kilim'') weaving is a traditional Turkish art form with roots in pre-Islamic times. During its long history, the art and craft of weaving carpets and tapestries in Turkey has integrated numerous cultural traditions. Apart from the Turkic design patterns that are prevalent, traces of Persian and Byzantine patterns can also be detected. There are also similarities with the patterns used in Armenian, Caucasian and Kurdish carpet designs. The arrival of Islam in Central Asia and the development of Islamic art also influenced Turkic patterns in the medieval period. The history of the designs, motifs and ornaments used in Turkish carpets and tapestries thus reflects the political and ethnic history of the Turks and the cultural diversity of Anatolia. However, scientific attempts were unsuccessful, as yet, to attribute a particular design to a specific ethnic, regional, or even nomadic versus village tradition.
