Turkic Minorities in China
İEdward J. Vajda
The Uighur (also spelled Uygur, Uigur; usually pronounced WE-ger in English)
The nearly six million Uighur today live in Xinjiang (which means "Western Frontier" in Chinese), where they constitute more than a three-fifths majority of the population. They are a Turkic people whose history stretches back to the 5th and 6th centuries AD. During this time, the Uighur and other Turkic peoples in what is today Mongolia, alone among all of the nomads of the steppes, developed an alphabetic writing system known as the Orkhon or Orkhon-Yenisei script. From 744 to 840 the Uighur controlled a powerful state. During this time they were converted to Persian Manicheism (a religion which viewed the world as an arena of opposing good and evil forces) and adopted a Sogdian script from Southwest Asia (see the chart of Central Asian writing systems in this packet). Under Chinese influence, this script came to be written vertically. In the early 13th century, the Uighurs submitted peacefully to Chingiz Khan, who borrowed their vertical script and adapted it to write Mongolian. The vertical Uighur alphabet was gradually replaced by Arabic letters.
The main religion among the Uighurs (as among all of the Turkic minorities of China) is Islam. The Uighurs have a rich literary and musical culture, and have much more in common with the Islamic, Turkic-speaking nations in former Soviet Central Asia than with the Chinese. Today the Uighur are the largest minority in northern China, and ethnic tension between them and the Chinese is a perennial problem for the Chinese government in Beijing.
so? Chinese consists of 56 ethnicities, Uighur is one of them. It's not pronounced as wigger, it's Wei-Wu-Er. Xinjiang doesn't mean "western frontier", it means "new territory"
