Singhasari ( or , ) was a Javanese Hindu kingdom located in east Java between 1222 and 1292. The kingdom succeeded the Kingdom of Kediri as the dominant kingdom in eastern Java. The kingdom's name is cognate to Singosari district of Malang Regency, located several kilometres north of Malang city. Etymology Singhasari (alternate spelling: Singosari) was mentioned in several Javanese manuscripts, including Pararaton. According to tradition, the name was given by Ken Arok during the foundation of the new kingdom to replace its old name, Tumapel, located in a fertile highland valley which today corresponds to the area in and around Malang city. It derives from Sanskrit word singha which means "lion" and sari which in Old Javanese could mean either "essence" or "to sleep". Thus Singhasari could be translated as "essence of lion" or "sleeping lion". Although the lion is not an endemic animal of Java, the symbolic depiction of lions is common in Indonesian culture, attributed to the influence of Hindu-Buddhist symbolism. Foundation Singhasari was founded by Ken Arok (1182–1227/1247), whose story is a popular folktale in Central and East Java. Most of Ken Arok's life story and also the early history of Singhasari was taken from the Pararaton account, which also incorporates some mythical aspects. Ken Arok was an orphan born of a mother named Ken Endok and an unknown father (some tales stated he was a son of god Brahma) in Kediri kingdom's territory. Ken Arok rose from being a servant of Tunggul Ametung, a regional ruler in Tumapel (present day Malang) to become a ruler of Java from Kediri. He is considered the founder of the Rajasa dynasty of both the Singhasari and later the Majapahit line of monarchs. He killed Tunggul Ametung and he was later assassinated by Anusapati, in revenge for killing his father, Tunggul Ametung. Ken Arok's son Panji Tohjaya assassinated Anusapati, but he in turn reigned only a few months in 1248 before his nephews revolted. These two, Ranga Wuni and Mahisha Champaka, ruled together under the names Vishnuvardhana and Narasimhamurti. Expansion In the year 1275, King Kertanegara, the fifth ruler of Singhasari who had been reigning since 1254, launched a peaceful naval campaign northward towards the weak remains of the Srivijaya in response to continuous Ceylon pirate raids and Chola kingdom's invasion from India which conquered Srivijaya's Kedah in 1025. The strongest of these Malaya kingdoms was Jambi, which captured
