2.) Kalingga
Historical records about the existence of the Kingdom of Kalingga are obtained from two main sources: the Chinese historical chronicles, as well as local manuscript historical records, complemented by local oral traditions mentioning the legendary queen named Queen Shima.
The Chinese records mention that in the 5th century, the Ho-Ling (or Kalingga) kingdom emerged, which is believed to have been located in the northern part of Central Java. Information about the Ho-Ling kingdom comes from inscriptions and records from China. In 752, the Ho-Ling kingdom became a vassal of Srivijaya because it became part of the Hindu trade network, along with Malayu and Tarumanagara, which had previously been conquered by Srivijaya. These three kingdoms became strong competitors to the Srivijaya-Buddhist trade network. Queen Shima is said to be the great-grandmother of Sanjaya, who later founded the Hindu Mataram kingdom.
