Sannaha was the mother of King Sanjaya, who established the Mataram Kingdom in the early 8th century CE.
Sanna was a wise and virtuous king and the island of Java had long been under his rule.
Amid a period of violence and confusion, Sanjaya (Sannaha's son)[1] ascended to the throne and established the Mataram Kingdom.
According to this book, she was the granddaughter of Queen Shima of Kalingga Kingdom and daughter of Mandiminyak, the second king of Galuh.
It also describes Sanjaya (who later ascended the throne of Galuh) to be the son of both King Sanna and Sannaha.
