The latest recorded use of Turkic alphabet was recorded in Central Europe's Hungary in 1699 CE. The Turkic runiform scripts, unlike other typologically close scripts of the world, do not have a uniform palaeography as, for example, have the Gothic runes, noted for the exceptional uniformity of its language and paleography. The Turkic alphabets are divided into four groups, the best known of them is the Orkhon version of the Enisei group. The Orkhon script is the alphabet used by the Göktürks from the 8th century to record the Old Turkic language. It was later used by the Uyghur Empire; a Yenisei variant is known from 9th-century Kyrgyz inscriptions, and it has likely cousins in the Talas Valley of Turkestan and the Old Hungarian script of the 10th century. Irk Bitig is the only known complete manuscript text written in the Old Turkic script. History Origins The origins of the Turkic peoples has been a topic of much discussion. Peter Benjamin Golden listed Proto-Turkic lexical items about the climate, topography, flora, fauna, people's modes of subsistence in the hypothetical Proto-Turkic Urheimat and proposed that the Proto-Turkic Urheimat was located at the southern Altai-Sayan region in Siberia. A possible genealogical link of the Turkic languages to Mongolic and Tungusic languages, specifically a hypothetical homeland in Manchuria, such as proposed in the Transeurasian hypothesis, by Martine Robbeets, has received support but also criticism, with opponents attributing similarities to long-term contact. Linguistic and genetic evidence strongly suggest an early presence of Turkic peoples in Mongolia. The proto-Turkic-speakers may have been linked to Neolithic East Asian agricultural societies in Northeastern China, which is to be associated with the Xinglongwa culture and the succeeding Hongshan culture, based on varying degrees of specific Northeast Asian genetic substratum among modern Turkic speakers. The East Asian agricultural roots of the Proto-Turkic language have been corroborated in multiple recent studies. According to historians, "the Proto-Turkic subsistence strategy included an agricultural component, a tradition that ultimately went back to the origin of millet agriculture in Northeast China". Around 2,200 BC, the agricultural ancestors of the Turkic peoples probably migrated westwards into Mongolia, where they adopted a pastoral lifestyle, in part borrowed from Iranian peoples. Given nomadic peoples such as Xiongnu, Rouran and Xianbei share underlying genetic ancestry "that falls into or close to the northeast Asian gene pool", the proto-Turkic language likely originated in northeastern Asia.
