Majapahit.

About Majapahit

Majapahit, also known as Wilwatikta, was a Javanese Hindu-Buddhist thalassocratic empire in Southeast Asia based on the island of Java. At its greatest extent, following significant military expansions, the territory of the empire and its tributary states covered almost the entire Nusantara archipelago, spanning both Asia and Oceania. After a civil war that weakened control over the vassal states, the empire slowly declined before collapsing in 1527 due to an invasion by the Sultanate of Demak. The fall of Majapahit saw the rise of Islamic kingdoms in Java.
