The ten-year-old child prince was raised to the throne by Siworawong. However, Siworawong continued to administer the country as Chaophraya Kalahom. After about a month, the government servants complained that there were in fact two rulers in the country, Athittayawong and Siworawong administering as a king, which could cause future danger for the country. They persuaded Siworawong to ascend to the throne so there would be only one king as per custom. Athittayawong was dethroned and Siworawong assumed the title Somdet Phrachao Prasat Thong.Rajanubhab, D., 2001, Our Wars With the Burmese, Bangkok: White Lotus Co. Ltd.,
