This article argues that the political thought of one of twentiethcentury Iran's foremost intellectuals, Jalal Ale Ahmad (1923-1969) and his seminal work Gharbzadegi (1962), often translated as 'Weststruck-ness' or 'Westoxication', can and should be understood through the critical study of race and racialisation. In contrast to the paradigms of 'nativism', 'Islamic atavism' and the demand for a return to 'cultural authenticity' that have traditionally framed the significance and reception of his thought, this article contends that Ale Ahmad's notion of gharbzadegi provides crucial insights into how predatory forms of colonial capitalism stratify the economic world order in accordance with what W.E.B. Du Bois famously called the 'colour line'. The article submits that Ale Ahmad's political thought sheds light upon the conditions of Eurocentric and racialised forms of knowledge production and immanent material practices, and how they structure the lived experiences of colonial and semi-colonial subjects, as well as providing a remarkable perspective on how 'race thinking' and the 'racial state' were conceived and institutionalised in twentieth-century Iran.
