This book is a succinct and critical account on the shariatisation of Indonesia, the largest Muslim country in the world. It is the first book in English to uncover and explain the shariatisation of Indonesia in a comprehensive way. With the abundant primary and secondary sources, this book is a reference for other scholars who conduct research on the inclusion of sharia into legal and public sphere of Indonesia. It comes with an important conclusion that the change of such a non-theocratic state like Indonesia into a theocratic state is highly possible when its law is penetrated by those who want to change the state system.
