Using a sample of Uyghurs in Turkey, we are testing the inclusion of social class, gender and Islamic customary practice on 'modernization theory'. 'Modernization theory', developed in the 1960's by applied social scientists from a Weberian-oriented tradition has had its own shortcoming: it proved to be too general to be useful. By specifying its application to the contemporary Islamic world, we hope to improve its utility. A questionnaire was developed concerning issues raised in the process of the modernization: ethnic identity, the maintenance of customary Muslim community practices, social class and gender differences. A sample is drawn from Uyghur students and professionals in Turkey in the spring of 2015, and then supplemented by visiting a Uyghur refugee camp in Turkey All the respondents were born in Xinjiang, in North West China and most of them were visiting exchange students from China or working-class Uyghur refugees as the situation in Xinjiang worsened after the 2009 uprising. The study compares the distinctive cultural-historical characteristics of Islamic modernization to that of Western modernization.
