According to the Chinese chronicle of the Sam Po Kong Temple, Ja Tik Su (Sunan Kudus?)
[1] Arya Pangiri was the son of Sunan Prawoto, the fourth king of Demak, who was killed by Rangkuti, a Jipang soldier who was very loyal to Arya Penangsang in 1547.
Arya Penangsang, the fifth king of Demak, was later killed by rioters sent by Hadiwijaya, the duke of Pajang.
Since then, Pajang has become a sovereign kingdom in which Demak is subordinate.
As and adult, Arya Pangiri was married to Ratu Pembayun, the eldest daughter of Sultan Hadiwijaya and became the duke of Demak.
