In childhood he was known as Chetthakuman (พระเชษฐากุมาร), meaning 'Chettha the Infant', or simply Chettha.

Reign Chetthathirat reigned for around a year according to Songtham's wishes conveyed to Okya Sri Vorawong or Phraya Siworawong – an influential royal page. The events were detailed by Jeremias van Vliet.

This proposed succession was objected to by some leaders in the kingdom, including the military minister, Samuha Kalahom Chao Phraya Maha Sena. Siworawong gained supporters in the government, and even used the services of Yamada Nagamasa the Okya Senaphimuk . Upon king Songtham’s death, Chetthathirat took the throne and Siworawong arrested and executed those who had opposed the idea. The new king made Siworawong military minister, as Okya Kalahom Siworawong or Chaophraya Kalahom.
