She was the daughter of
Maha Thammaracha, viceroy of
Phitsanulok and later King of
Ayutthaya and his wife
Wisutkasat; elder sister of the princes
Naresuan and
Ekathotsarot who later both became kings of Ayutthaya, too. On her maternal side she was a granddaughter of King
Chakkraphat and Queen
Suriyothai. In 1564, her father became a vassal of King
Bayinnaung of Pegu in Burma. Her brothers were taken to the Peguan court to serve as pages and guarantee for the loyalty of their father, as was usual at the time.
Thai narrative According to the common narrative in Thailand, in 1571, Suphankanlaya agreed to marry Bayinnaung to become one of his minor wives. This bond, too, should consolidate her father's allegiance to the Burmese king. Her brothers, instead, could return home. She had two children with Bayinnaung. After the king's death in 1581, she became the wife of his son and successor
Nanda. In 1584, her father revolted against Nanda. He revoked the oath of allegiance to the Burmese king and it came to war. After her father's death in 1590, her brother Naresuan carried on the fight. In 1593, Naresuan defeated and killed Nanda's son
Mingyi Swa in a legendary
duel on elephants' backs. When Nanda learnt of his son's death, according to the common narrative in Thailand, he became enraged and struck Suphankanlaya, who was eight months pregnant with his child, dead.
Burmese records The
Burmese chronicles mention her only in passing. According to the records, her title was Bra Inda Devi or Phra Indra Devi (, ) and her personal name was Amyoyon (, ). She was presented to the king at the Pegu court on 22 January 1567. They had a daughter named Min A-Htwe (, ). Moreover, the chronicles make no mention of her subsequent marriage to Nanda. Her name does not appear in the chronicles' list of queens, junior queens or concubines of Nanda. == Popular cult ==
