Chai of Lan Na
Thao Chai, Saikham or Mueangchaichao was the 13th king of Lan Na from the Mangrai dynasty. He reigned from 1538 to 1543. He seized power from his father, Ket. After reigning for just five years, he was assassinated by a group of nobles who claimed that he lacked the legitimacy to the throne. The nobles then invited Ket to return and resume the throne for a second time. Chai’s reign was marked by great unrest, including rebellions and infighting among various noble factions fighting for power.
Accession to the Throne
Chai’s father, Ket, came into conflict with the nobility in 1535. The nobles of Lampang led a rebellion, as mentioned in one passage:“…the ministers, such as Muen Samlan of Lampang, and his son, Muen Samlan believed Muen Luang Channanok and Muen Yi Ai were conspiring to betray King Ketchettharaj. The King found out and ordered Muen Soi Samlan to be executed that very day…”This shows that regional nobles were dissatisfied with the king, and tensions intensified until, in 1538, the nobles gained power over the monarch and deposed Ket and exiled him to Muang Noi.
Following this event, the nobles invited Chai to ascend the throne in his father’s place. He began his reign in 1538 at the age of 24.
Assassination
However, not long after his coronation, he was assassinated. Phra That Hariphunchai Chronicle recounts:“…Phaya Saikham held the throne for six years. He had many daughters and many sons. In the year of the Tiger, 11th lunar month, 1st waning moon, Sunday, sword-wielding townsmen killed him entirely at the Minor Palace…”Chai was murdered in his palace, along with his family, by nobles. The Chiang Mai Chronicle explains the motive:
“…he ruled unlawfully without royal legitimacy. The ministers and officials together had Prince Chai killed in the year of the Rabbit, Chula Sakarat 905…”Nonetheless, evidence surrounding the assassination is scarce, and it remains unclear who exactly was involved.
