Kingdom of Janggala

The Kingdom of Janggala was one of the two Javanese states created in 1045 when King Airlangga abdicated and divided Kahuripan between his two sons. Janggala received the north-eastern half, including the Brantas delta and the port of Hujung Galuh, the site of modern Surabaya, while Kediri took the west. The name probably derives from Hujung Galuh, meaning 'Cape Diamond', and Chinese sources rendered it as Jung-ya-lu. Little is known of the kingdom because its western neighbour Kediri was the more powerful and better documented. Janggala and Kediri were reunited when Kameswara of Kediri married a Janggala princess, after which Janggala ceased to exist as a separate kingdom; the union is usually dated to 1136. Later tradition remembered Airlangga's division as the origin of the two realms, and the former Janggala lands remained part of the Brantas valley heartland that passed to Singhasari and then Majapahit. The port of Hujung Galuh stayed important through those later states.
