This article, through comparative historical analysis, examines the traditional marriage rituals of the Dungan diaspora in Kazakhstan. Dungans are Chinese-speaking Muslims who were forced to migrate to present-day Kazakhstan, Kyrgyzstan, and Uzbekistan after the defeat of their revolt against the Qing dynasty from 1877 to 1888. The article focuses on the diversity of wedding ceremonies in three zones where Dungan settled in Kazakhstan: Zhalpak Tobe and Sortobe, two rural areas in the Zhambyl region; and Zaria Vostok, near the city of Almaty. I find that the local variations in traditional wedding ceremonies stem from their close intercultural and social cooperation with non-Dungan peoples—primarily Kazakhs, Uzbeks, Uyghurs, and Russians. The example of wedding rituals shows that, while Dungan existence in another cultural environment has stimulated the consolidation of their ethnic group, preserving many of the traditional archaic cultural features, it has also led to the transformation of the marriage ceremonies. I address a much-neglected pathway—the nature of borrowed elements in Dungan wedding rituals—and ask why the extent of borrowing varies from community to community even though the Dungan arrived from China with similar traditions.
