Piang of Yonok

Piang (Thai: พระองค์เพียง) was a legendary Tai Yuan monarch of the Singhanavati clan, the ruling house of the Yonok Kingdom, traditionally dated to the 4th century CE. According to the Legend of Singhanavati, Piang ascended the throne following the death of his father, Ping II, in 259^[1]: 72 of the Śaka Era (SE),^[2] corresponding to 337 CE, at the age of 24.^{[1]: 72 [3]: 77} This chronology places his birth in 235 SE (313 CE).

The same tradition records that Piang had a single son, Bhrngaraja, who succeeded him in 277 SE (355 CE).^{[1]: 72 [3]: 77} However, Bhrngaraja’s reign was soon disrupted by a rebellion led by Phraya Khom, the vassal ruler of Umongasela,^[2][4] culminating in the seizure of Yonok in 279 SE (357 CE).^{[1]: 73–4 [3]: 78}
