 According to the Portuguese explorer, Tome Pires, in the early 16th century the port of Bantam (Banten) was an important port within the Kingdom of Sunda along with the ports of Pontang, Cheguide (Cigede), Tangaram (Tangerang), Calapa (Sunda Kelapa) and Chimanuk (estuarine of the Cimanuk river).In 1527, just as the Portuguese fleet was arriving off the coast, newly converted Javanese Muslims under Sunan Gunungjati captured the port of Banten and the surrounding area from the Sundanese leaders and established the Sultanate of Banten.The center of this sultanate, according to the Portuguese historian João de Barros, was Banten which was a major port in Southeast Asia rivaling Malacca and Makassar.
