Trenggana (1521–1546), also called Trenggono, was the third Sultan of Demak after he succeeded Pati Unus.
Sultan Trenggana was crowned by Sunan Gunungjati, one of the Wali Songo who spread Islam in Java.
He made these territories the new sultanate of Banten, a vassal state of Demak under the reign of Hasanudin.
Trenggana spread Demak's influence eastwards and during his reign he conquered the remains of the last Javanese Hindu-Buddhist state, the once mighty Majapahit.
Demak was able to Islamize and subjugate other major ports of the interior of East Java.
