Jakarta is Indonesia's capital and largest city. Located on an estuary of the Ciliwung River, on the northwestern part of Java, the area has long sustained human settlement. Historical evidence from Jakarta dates back to the 4th century CE, when it was a Hindu settlement and port. The city has been sequentially claimed by the Indianized kingdom of Tarumanegara, the Hindu Kingdom of Sunda, the Muslim Sultanate of Banten, and by Dutch, Japanese and Indonesian administrations. The Dutch East Indies built up the area before it was taken during World War II by the Empire of Japan and finally became independent as part of Indonesia.
