King Jai Jettha IV died in 1729, and his co-regent Ang Im abdicated in favor of his son Sattha, who was married to his wife’s half-sister Sijhata, who thereby became queen. It appears that queen Sijhata lived separated from king Sattha. An inscription describe how an anuj khshatri, ‘young queen’ established her own court at Samron Sen, attended the children and nephews and nieces of the king. This woman is identified with Sijhata.
