Setthathirath known as Chaiyachettha or Chaiyaset or Jayajestha, Son of the King Photisarath of Lan Xang, he was crowned King of Lanna after the death of his grandfather, Ketklao the previous King of Lanna, who died without a male heir to the throne and gave his daughter Princess Yotkhamtip in marriage to his father King Photisarath of Lan Xang.
In 1548 King Setthathirath had taken Chiang Saen as his capital.
Setthathirath claimed that taking the statue would allow his relatives the opportunity to venerate the image and make merit.
The Nobles of Lanna felt that Setthathirath had stayed away too long, and sought another descendant of Mangrai dynasty to take the throne in 1551.
In 1553 King Setthathirath sent an army to retake Lanna from Mekuti but was defeated.
Again in 1555 King Setthathirath sent an army to retake Lanna at the command of Sen Soulintha, and managed to take Chiang Saen.
In 1560, King Setthathirath formally moved the capital of Lan Xang from Luang Prabang to Viangchan, which would remain the capital over the next two hundred and fifty years.
The Burmese had planned on the reinforcements however and Setthathirath fell into a trap.
The Burmese rallied and were able to destroy the divided forces, and Setthathirath had to retreat toward Viangchan.
Just as in 1565, Setthathirath began a guerrilla campaign from his base near the Nam Ngum River, northeast of Vientiane.
In 1570 Bayinnaung retreated, Setthathirath counterattacked and more than 30,000 were taken prisoner, along with 100 elephants, and 2,300 pieces of ivory from the retreating Burmese.
In 1571, a conspiracy between Lord Phya Nakhon and the former abbot of Wat Maximavat, who held personal grudges against Setthathirath, led to the king's murder in the southern frontier of the country.
Setthathirath declared independence from the Burmese in 1593, but suffered several attacks from them throughout his reign.
