The future queen was the second child of Prince Minkhaung of Pyinzi and his first wife Shin Mi-Nauk.
His father was a son of then King Swa Saw Ke of Ava while his mother was a daughter of Sawbwa (Chief) Tho Ngan Bwa of Mohnyin.
[note 2] Razadarit had Anawrahta executed, and raised Saw Pyei Chantha, as one of his junior queens.
[5] The brazen act greatly incensed her father, and led to the renewed war between the two kingdoms for the next decade.
The queen joined her paternal aunt Thupaba Dewi, who had been given to Razadarit in a marriage of state as part of the truce of 1403, in the Hanthawaddy king's harem.
