Nakhon Noi briefly occupied the throne of Lan Xang from 1582 to 1583 on the death of his father Sen Soulintha, who himself had been appointed as a vassal to the Toungoo Empire from 1580 to 1582.
Other versions record that he simply had made enemies at court, or was perceived as illegitimate because (like his father Sen Soulintha) he was of common origins.
[2] The chronicles again agree that it was only after the period of succession crisis that a petition was finally sent in 1591 to Nanda Bayin by the Lao sangha and Lan Xang court asking for Prince No Muang, the son and legitimate heir of Setthathirath, to be appointed as king.
In any event Sen Soulintha became deeply distrusted by the population, and during the third Burmese invasion led by Bayinnaung both he and his son Nakhon Noi were arrested (possibly by the Lao) and taken back to Pegu as prisoners.
[4][16] In Pegu, the previous year Bayinnaung had died and the Taungoo Empire had passed into the hands of his son Nanda Bayin, who struggled with his own court.
According to some sources his reign was characterized by a brief tyranny, although it is equally possible he was simply another victim of factionalism at court, or lacked legitimacy due to his common origins.
[17] With Prince No Muang in captivity, an interregnum occurred until a senior delegation of the Lao sangha and Lan Xang court came to Nanda Bayin to request his return.
After fifteen years of captivity in Pegu, the son of Setthathirath, Prince No Muang, returned to Lan Xang as King Nokeo Koumane.
