Parameswara, the founder of Melaka, apparently converted to Islam towards the end of his life. Whether or not he did so out of conviction, his action made commercial sense. Islam was the dominant religion amongst merchants in the Indian Ocean. As travellers and traders, the merchants found much appeal in the fact that Islam's God was everywhere, not tied to a single place like many traditional deities, as well as in Islam's insistence on the equality of believers.
As the first great state in Southeast Asia to convert to Islam, Melaka became the model for newer Muslim states, its cultural influence spreading far beyond its area of political control.
