Many recent works on Muslim societies have pointed to a growing ‘deculturalization’ and ‘purification’ of Islamic practices. Instead, by exploring themes such as architectural designs, preaching activities, political engagement and cultural celebrations, this book describes and analyses the formation and negotiation of Chinese Muslim cultural identities in Indonesia today – a rapidly evolving environment where there are multiple ways of being or not being Chinese and Muslim. By engaging with the notions of ‘inclusive Chineseness’ and ‘cosmopolitan Islam’, this book gives insights not only into the cultural politics of Muslim and Chinese identities in Indonesia today but also into the possibilities and limitations of ethnic and religious cosmopolitanism in many other contemporary societies.
