One of the classical accounts on the coming and first establishment of Islam in Indonesia runs as follows: Already a long time before the birth of Islam a mighty stream of colonisation started from Hindustan towards Java and surrounding islands. This stream definitely dominated the culture of this area and its influence is felt until today. After part of the Hindus had accepted Islam, these Indian Muslims were active in the trade with the archipelago and part of them also settled in this area. These traders and emigrants brought Islam into the Indian Archipelago. It is true, that already before this period some other Muslim nations sought articles of trade from the East-Indies and even established small settlements there: surely there resulted no permanent religious influence from these settlements. Islam, such as received by the Indonesians, therefore already experienced a process of adaptation towards the world of Hinduism. This made it easier for this new religion to accommodate itself once again to a degenerated Hinduism. Islam in the East-Indies unmistakably shows the signs of this Indian origin.
