The Banten Sultanate was an Islamic trading kingdom founded in the 16th century and centred in Banten, a port city on the northwest coast of Java; the contemporary English name of both was Bantam. It is said to have been founded by Sunan Gunungjati, who had previously founded Cirebon. Once a great trading centre in Southeast Asia, especially of pepper, the kingdom reached its apogee in the late 16th and mid-17th centuries. By the late 17th century its importance was overshadowed by Batavia, and finally annexed to Dutch East Indies in 1813.
