There is a population of Uyghurs in Kyrgyzstan, who mostly came to the country in three separate migrations throughout the 19th and 20th centuries. According to official statistics, they make up about 0.9% of the national population.Uyghur migration to Kyrgyzstan can be analysed in three waves. The first wave began in the late 19th century. Some Uyghurs from Kashgar came with the Dungans to the Ferghana Valley in the aftermath of the 1862-1877 uprising in northwest China; the total number to settle there (including both Uyghurs and Dungans) was about 7,000 people, according to contemporary Russian reports. Later, in the early 20th century, Uyghurs, Dungans, and Chinese alike came as migrant workers to find employment in coal mines and cotton mills.
