The first European fleet, four Portuguese ships from Malacca, arrived in 1513 while looking for a route for spices. The Sunda Kingdom made an alliance treaty with the Portuguese by allowing them to build a port in 1522 to defend against the rising power of Demak Sultanate from central Java. In 1527, Fatahillah, a Javanese general from Demak attacked and conquered Sunda Kelapa, driving out the Portuguese. Sunda Kelapa was renamed Jayakarta, and became a fiefdom of the Banten Sultanate, which became a major Southeast Asian trading centre.
