The Turkic migration as defined in this article was the expansion of the Turkic peoples across most of Central Asia into Europe and the Middle East between the 6th and 11th centuries AD (the Early Middle Ages). Their prehistoric point of origin was the hypothetical proto-Turkic region of the that includes North China and Inner Mongolia.Certainly identified Turkic tribes were known by the 6th century and by the 10th century most of Central Asia was settled by Turkic tribes. The Seljuq dynasty invaded Anatolia starting in the 11th century, ultimately resulting in permanent Turkic settlement there. Meanwhile, other Turkic tribes either ultimately formed independent nations, such as Kyrgyzstan, Turkmenistan, Uzbekistan and Kazakhstan or formed enclaves within other nations, such as Chuvashia. Turkic peoples also survived in their original range, such as the Uyghurs in China and the Sakha Republic of Siberia, as well as in other scattered places of the Far East and Central Asia.
