Islam in Indonesia can be traced back to the 7th century when a Muslim tomb was found in Barus in the western part of Sumatra Island. Islam was spread in the archipelago through commercial and cultural ways. Muslim communities then were created in some areas. A number of Islamic kingdoms emerged since the 11th century and faced new challenges and struggled when the European colonialists come to the archipelago. Islam still survived up today in the country because many Muslims have been ready to sacrifice themselves as ‘syuhada’ not only for the existence of Islam but also for the independence of the country througout the history.
Now, Muslim community in Indonesia is the largest in the world. Many attractive developments and features of Islam in Indonesia may be regarded as the primal contributions to the development of Islam in the modern world.
