Amarindra (Thai: อมรินทรา, RTGS: Amarinthra, Amarindrā; 15 March 1737 – 25 May 1826) was the queen consort of King Phutthayotfa Chulalok (Rama I), the founder of the Chakri dynasty.
[2] Nak was born in 1737 to a local patron of Bang Chang named Thong and his wife San.
[3] She was then married to Thong Duang the Luang Yokkrabat of Ratchaburi (future Rama I) around 1760 to avoid being taken as a court lady to King Ekkathat.
The Somdet Chao Phraya was enraged with the incident and threatened to murder Nak with a sword,[4] only with the help of her son Chim (the future Rama II) was Nak able to flee to the Thonburi Palace to live with her daughter Chimyai (concubine to King Taksin).
The Somdet Chao Phraya became a monarch in 1782 and most of Taksin's sons were executed except for Prince Kasatranuchit who was his own grandson.
