Kingdom subsequently became the ruling power of the region, as recorded on the Kebon Kopi II inscription (AD 932). An Ulama, Sunan Gunung Jati, settled in Cirebon, intending to spread Islam in the town. Meanwhile, the Sultanate of Demak in Central Java grew to become a threat to the Sunda kingdom. To defend against the threat, Prabu Surawisesa Jayaperkosa signed the Luso-Sundanese Treaty with the Portuguese in 1512. In return, the Portuguese were granted access to build fortresses and warehouses in the area, as well as forming trading agreements with the kingdom. This first international treaty of Sunda Kingdom with the Europeans was commemorated by the placement of the Padrao stone monument at the bank of the Ciliwung River in 1522. Although the treaty with the Portuguese had been established, it could not come to realisation. Sunda Kalapa harbour fell under the alliance of the Sultanates of Demak and Cirebon (former vassal state of Sunda kingdom) in 1524 after forces under Paletehan alias Fadillah Khan had conquered the city. In 1524–1525, troops under Sunan Gunung Jati also seized the port of Banten and established the Sultanate of Banten which was affiliating with Demak. The war between the Sunda kingdom with Demak and Cirebon sultanates continued for five years until a peace treaty was made in 1531 between King Surawisesa and Sunan Gunung Jati. From 1567 to 1579, under the last king Raja Mulya, alias Prabu Surya Kencana, the Sunda kingdom declined, under pressure from Sultanate of Banten. After 1576, the kingdom could not maintain control over its capital at Pakuan Pajajaran (present-day Bogor), and gradually the Sultanate of Banten took over the former Sunda kingdom's territory. The Mataram Sultanate from Central Java also seized the Priangan region, the southeastern part of the kingdom. In the 16th century, Dutch and British trading companies established trading ships in western Java after the fall of the Sultanate of Banten. For the next three hundred years, western Java fell under the Dutch East Indies' administration. West Java was officially declared as a province of Indonesia in 1950, referring to a statement from Staatblad number 378. On 17 October 2000, as part of nationwide political decentralisation, Banten was separated from West Java and made into a new province. There have been recent proposals to rename the province Pasundan ("Land of the Sundanese") after the historical name for West Java. Administrative divisions Since the creation of
