The city was settled in the 10th century by the Kingdom of Janggala, one of the two Javanese kingdoms that was formed in 1045 when Airlangga abdicated his throne in favor of his two sons. In the late 15th and 16th centuries, Surabaya grew to be a duchy, a major political and military power as well as a port in eastern Java, probably under the Majapahit empire. At that time, Surabaya was already a major trading port, owing to its location on the River Brantas delta and the trade route between Malacca and the Spice Islands via the Java Sea. During the decline of Majapahit, the lord of Surabaya resisted the rise of the Demak Sultanate and only submitted to its rule in 1530. Surabaya became independent after the death of Sultan Trenggana of Demak in 1546.
