Mahmud Kashgari (1008–1105), whose full name is Mahmud ibn Hussain ibn Muhammad Kashgari, was a renowned 11th-century Uyghur linguist, Turcologist, and philosopher. He was born in Aziq Village, southwest of today's Kashgar City, Xinjiang. From a young age, he studied at the Royal Academy of the Karakhanid Dynasty's capital, Kashgar, where he mastered Arabic and Persian. In 1058, after his father was killed in a palace coup, he wandered for 14 years, traveling through Central Asian cultural centers such as Bukhara, Samarkand, and Nishapur in Persia, seeking knowledge from scholars and accumulating a vast amount of material. Between 1072 and 1074, he compiled the Compendium of the Turkic Dialects in the Abbasid capital, Baghdad, and dedicated it to the Caliph. In 1080, he returned to his hometown to engage in academic research and education, where he remained until his death in 1105.

The painting Mahmud Kashgari was created by the famous Uyghur painter Hazi Amat. Mahmud Kashgari's most famous work, the Compendium of the Turkic Dialects, is the world's first systematic study of the Turkic languages, written in Arabic. It covers grammar, vocabulary, and phonetics of the Turkic languages. Through rich linguistic materials, the dictionary extensively introduces the political, economic, cultural, historical, philosophical, and ethnographic aspects of the Uyghur and other Turkic peoples during the Karakhanid era, making it an encyclopedia of the Turkic tribes.

Hazi Amat grew up in Kashgar listening to stories of this sage and had a deep understanding of the scholar who "abandoned wealth and honor" to travel extensively. He was well-versed in both civil and military affairs and had a passion for learning. In 1981, Hazi Amat created a portrait of Mahmud Kashgari, depicting him as a scholar with a weathered yet refined appearance, strong personality, and bravery. In 2005, to commemorate the 1000th anniversary of Mahmud Kashgari's birth, Hazi Amat created a standard portrait of Mahmud Kashgari. During the creation process, he referred to the clothing and headwear of the period (the Karakhanid era) and conducted thorough research into the background of the sage.

The Compendium of the Turkic Dialects is an invaluable resource for studying the history, geography, folklore, social life, and literary arts of the Turkic-speaking peoples of Central Asia. It not only preserves linguistic and cultural knowledge of the Turkic tribes in present-day Xinjiang, China, and Central Asia but also provides important references for researching the history, geography, products, and customs of the Turkic peoples. Additionally, the dictionary contains rich philosophical content, such as proverbs, idioms, sayings, folk songs, and poetry.

Mahmud Kashgari is a scholar of great significance in the cultural history of the Uyghur people. His Compendium of the Turkic Dialects is not only a monumental work in the treasure trove of Chinese culture but also a jewel in the world's cultural and artistic heritage. Through its rich linguistic materials, the work extensively introduces the political, economic, cultural, historical, philosophical, and ethnographic aspects of the Uyghur and other Turkic peoples during the Karakhanid era, providing an important perspective and resource for studying ancient Chinese history and culture.
