Spread of Islam in Indonesia

The history of the arrival of Islam in Indonesia is somewhat unclear.[1] One theory states that Islam arrived directly from Arabia as early as the 9th century, during the time of the Umayyad and Abbasid caliphates. Another theory credits Sufi travelers for bringing Islam in the 12th or 13th century, either from Gujarat in India or from Persia.[2] Before the archipelago's conversion to Islam, the predominant religions in Indonesia were Hinduism (particularly its Shaivism tradition) and Buddhism.[3][4]

The islands that now constitute Indonesia have been recognized for centuries as a source of spices such as nutmeg and cloves, which were key commodities in the spice trade long before the Portuguese arrived in the Banda Islands in 1511.[5][6] Due to the archipelago's strategic place as the gateway between the Muslim world and Imperial China, it became a busy international hub for merchants engaged in many forms of trade.[7] It became a place where different peoples shared their respective cultures, including Islam.


Despite being one of the most significant developments in Indonesian history, evidence about the coming of Islam to Indonesia is limited; there is considerable debate among scholars about what conclusions can be drawn about the conversion of Indonesian peoples.[8]: 3  The primary evidence, at least of the earlier stages of the process, are gravestones and a few travelers' accounts, but these can only show that indigenous Muslims were in a certain place at a certain time. This evidence cannot explain more complicated matters such as how lifestyles were affected by the new religion or how deeply it affected societies. It cannot be assumed, for example, that because a ruler was known to be a Muslim, therefore the Islamization of that area was widespread. Nevertheless, a clear turning point occurred when the Hindu Majapahit empire in Java fell to the Islamised Demak Sultanate. In 1527, the Muslim ruler renamed the newly conquered Sunda Kelapa as Jayakarta (meaning "precious victory") which was eventually contracted to Jakarta.


The spread of Islam was slow.[9] The limited evidence that is currently known suggests that the spread of Islam accelerated in the 15th century. One of the defining characteristics of the spread was that it was achieved through generally peaceful means.[10][11][12][13] As Muslim traders settled in coastal areas, they began to assimilate with the local population. Soon new Muslim communities were created, as evidenced by the travel journals of Ibn Battuta, Zheng He, and Marco Polo. Many Muslims inter-married with royalties, with their descendants establishing various sultanates in Sumatra and Java.


Dominant kingdoms included Mataram in Central Java, and the sultanates of Ternate and Tidore in the Maluku Islands to the east. By the end of the 13th century, Islam had been established in North Sumatra; by the 14th in northeast Malaya, Brunei, the southern Philippines and among some courtiers of East Java; and the 15th in Malacca and other areas of the Malay Peninsula. Although it is known that the spread of Islam began in the west of the archipelago, the fragmentary evidence does not suggest a rolling wave of conversion through adjacent areas; rather, it suggests the process was complicated and slow.

("The Story of the kings of Pasai") – an Old Malay text that tells how Islam came to "Samudra" (Pasai, northern Sumatra), where the first Indonesian Islamic state was founded.

Hikayat Raja-raja Pasai

("Malay History") – an Old Malay text, which like Hikayat Raja-raja Pasai tells the story of the conversion of Samudra, but also tells of the conversion of the King of Malacca.

Sejarah Melayu

("History of the land of Java") – a generic name for a large number of manuscripts, in which the first Javanese conversions are attributed to the Wali Sanga ("nine saints").

Babad Tanah Jawi

("History of Banten") – a Javanese text containing stories of conversion.

Although time frames for the establishment of Islam in Indonesian regions can be broadly determined, the historical primary sources cannot answer many specific questions, and considerable controversy surrounds the topic. Such sources do not explain why significant conversions of Indonesians to Islam did not begin until after several centuries of foreign Muslims visiting and living in Indonesia, nor do they adequately explain the origin and development of Indonesia's idiosyncratic strains of Islam, or how Islam came to be the dominant religion in Indonesia.[8]: 8  To fill these gaps, many scholars turn to Malay and Indonesian legends surrounding Indonesian conversion to Islam. Ricklefs argues that although they are not reliable historical accounts of actual events, they are valuable in illuminating some of the events is through their shared insights into the nature of learning and magical powers, foreign origins and trade connections of the early teachers, and the conversion process that moved from the elite downwards. These also provide insight into how later generations of Indonesians view Islamisation.[8]: 8–11  These sources include:


Of the texts mentioned here, the Malay texts describe the conversion process as a significant watershed, signified by formal and tangible signs of conversion such as circumcision, the Confession of Faith, and the adoption of an Arabic name. On the other hand, while magical events still play a prominent role in the Javanese accounts of Islamisation, such turning points of conversion as in the Malay texts are otherwise not as evident. This suggests a more adsorptive process for the Javanese,[8]: 9  that is consistent with the significantly larger syncretic element in contemporary Javanese Islam in comparison to the relatively orthodox Islam of Sumatra and Malaysia.
