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.

According to the records, her title was Bya Eindra Dewi (ဗြဣန္ဒဒေဝီ, [pʰjá ʔèiɴdɹà dèwì])[note 1] and her personal name was Amyoyon (အမျိုးရုံ, [ʔə mjó jòʊɴ]).

She then asked a historian to research the chronicles for accounts of the princess and a successful romantic novelist to popularise Suphankanlaya's story in an easy-to-read way.

This did not stop large parts of the Thai public from developing a cult around the supposed heroine, worshipping her images and votive objects.

[5] The spread of Suphankanlaya worship has to be seen in the context of the rise of Thai nationalist (particularly anti-Burmese) sentiments at that time of economic crisis.

[6] It is similar to the emergence of a cult around her grandmother Queen Suriyothai who is (ahistorically) venerated as a strong warrior heroine who sacrificed herself for the sovereignty of the nation, as well.

The Third Army command in her presumed native city of Phitsanulok was the first to erect a monument to her and commissioned a biography in 1998, in which the alleged cruelty of her Burmese husband was emphasised.
