Scholars of Indonesian history seldom discuss the historical changes that occurred on the north coast of Java between the 15^(th) and 17^(th) centuries, between the fall of Majapahit and the rise of Mataram. This can be attributed, in part, to the lack of surviving historical materials, and in part to a reluctance to mention the influence of Chinese Muslims on the Islamization of Java. In this article, the author hopes to explore this important period in Javanese history. Relying on The Malay Annals of Semarang and Cirebon, Sanusi Pane's Sedjarah Indonesia (History of Indonesia), and related studies, it seeks to reconstruct the Chinese Sultanates established on Java's north coast between the 15^(th) and 17^(th) centuries. It will focus its discussion and analysis on the rise and fall of Demak, Pajang, Cirebon, and Banten.
