"In the course of the centuries, Islam spread throughout the Javanese population, until its adoption by the last large district, the “east hook,” was accomplished in the late eighteenth century. This process seems on the whole to have been peaceful, or as peaceful as it could have been in a period of Javanese history characterized by almost incessant warfare. Conversion by arms may have occurred when a Muslim dignitary defeated a non­ Muslim, whereupon the vanquished and his people would presumably have embraced Islam."
