Dungan: a Sinitic language written with the Cyrillic alphabet
The Dungan people are a group of Sinitic speakers whose Muslim ancestors fled to Central Asia (mainly in parts of what are now Kyrgyzstan and Kazakhstan) over a century ago when the Qing (Manchu) government suppressed their revolt (1862-1877), one of many Muslim uprisings in the course of Chinese history since Islam arrived in East Asia during the Middle Ages.
When they came to Central Asia, the Dungans were mostly illiterate peasants from northwest China who spoke a series of topolects from Shaanxi, Gansu, and other areas. From 1927 to 1928, they wrote their language with the Arabic alphabet, and from 1928-1932 they used the Latin alphabet. In 1952-53, the Soviet government created for the Dungans a writing system based on the Cyrillic alphabet, which they continue to use till today.
