Salafism has never ceased to feature prominently throughout the history of Islam. As in many parts of the world today, Salafism in Indonesia remains largely misunderstood and even less is known about its origins. This book sheds light on the origins of Salafism in Indonesia by discussing the various definitions of Salafism, addressing misconceptions and assumptions about its origins and actors in the archipelago, and proposing that puritan Salafism was only introduced into Indonesia in the last 20-30 years. As a first look at the topic, this book should be particularly useful to experts on Islam in Indonesia who are interested in pursuing in-depth research in the area. It has also been written for general readers with an interest in gaining a quick insight into Salafism and its role in Muslim society.
