Somdet Phra Boromma Trailokanat Songtham, of the House of Sukhōday, is the King of Ayutthaya from 1611 to 1628.
His reign is marked as prosperity after the First Fall of Ayutthaya and sees the commencement of trade with foreign nations, especially the Dutch and the Japanese.
Songtham fills his guards with foreign mercenaries, most notably the Japanese adventurer Yamada Nagamasa.
Sources vary concerning Songtham’s origin.
The Royal Secretariat’s Chronicles (1912) named him Prince Si Sin but other chronicles named him Prince Inthraracha.
The prince was a minor prince born to Ekatotsarot with one of his concubines.
As a minor prince, Inthraracha had pursued religious ordination and become a respected monk with the name Pimol Anantapreecha.
