King of Tilokaraj, one of the Mengrai dysnasty, was the ninth king of Chiang
Mai form 1985 to 2030 B.E. He had only one son, Tao Sri Boonroeng. King
Tilokaraj was told by his favourite consort that Tao Sri Boonroeng who is
twenty years old was trying to overthrow him and become a king himself.
Consequently, King Tilokaraj sent his son away to rule Chiang Rai and
Chiang Sean which were under the domination of Chiang Mai at that time.
At Chiang Rai, Tao Sri Boonroeng had a son. This child was born while his
mother was travelling and staying on the top of a mountain in Chiang Rai
(Yod Dok Bua). So, Tao Sri Boonroeng named his son as Yod Chiang Rai
which means the top of Chiang Rai.
Some years later, the King was again told by his consort, Nang Hau Mook, that Tao Sri Boonroeng was trying to rebel against him. He then decided to murderhis son and make his grandson, Chao Yod Chiang Rai , ruler of Chiang Rai.
In B.E. King Tilokaraj died and Chao Yod Chiang Rai was crowned King of
Chiang Mai. After he had arranged the affairs of the Kingdom, he then
stared to investigate the case of his father’s death, to search for the
persons who had accused his father of rebellion and thereby also caused
his mother’s mental illness. On discovering the persons who were
responsible for the sad fate of father and mother, the King sentenced
them to dead. However, as a devout follower of Lord Buddha, he wished
to make recompensation for this action.
