Somdet Phra Boromma Trailokkanat (Thai: สมเด็จพระบรมไตรโลกนาถ) (1431–1488) was the king of Ayutthaya from 1448 to 1488. He was also known as Phra Chao Chang Phueak (Thai: พระเจ้าช้างเผือก) for his gain of auspicious white elephant. His reign was also known for a massive reforms of Siamese bureaucracy and a successful campaign against Lanna. He was also revered as one of the greatest monarchs of Siam.
King of Sukhothai
Prince Ramesuan (not to be confused with King Ramesuan r. 1369–1370) was born in 1431 to King Borommaracha Thirat II or Chao Sam Phraya and his queen from the Kingdom of Sukhothai. He became the Uparaja (lit. vice-king of crown prince) in 1438. When his cousin, Thammaracha IV of Sukhothai died in 1438, Ramesuan was then technically the king of Sukhothai – though he was too young to be crowned. Upon reaching majority, Borommaracha II sent Ramesuan to Pitsanulok to assume the Sukhothai throne.
Borommaracha II died in 1448, Prince Ramesuan was then crowned as King Trailokkanat of Ayutthaya – thus a personal union between Sukhothai and Ayutthaya.
Trailokkanat reformed the Siamese bureaucracy – the system lasted well into the 19th century. He separated civil and military officials, giving them titular ranks and feudal ranks to create the hierarchy of nobility. He also established the circle of cities ranging from the Inner Cities, Outer Cities, to Tributaries. Trailokkanat also ceased the tradition of appointing royal princes to govern cities, as they had always clashed with each other in times of succession. Trailokkanat promulgated the Ayutthayan Law in 1458.
Also in his reign in 1454, the Thai royal and noble titles were first codified under the "field-power" system called Sakdina (ศักดินา). Fields (Na) were reckoned in Rai (a plantation, equal to 1600 square metres under metrificattion of traditional measures.) Petty officials were accorded a Sakdi (power), of 1, 50 or 400, extending up to 100,000 rai for the Uparat (heir-apparent). This system continued until the reforms of King Chulalongkorn at the beginning of the 20th century.
Trailokkanat adopted the position of Uparaja, translated as "viceroy" or "underking", usually held by the king's senior son or full brother, in an attempt to regularize the succession to the throne — a particularly difficult feat for a polygamous dynasty. In practice, there was inherent conflict between king and uparaja, and frequent disputed successions.
Tributary relationships of Cities
In 1468, Trailok adopted a Mandala-style tributary system, and ranked the cities recognizing him as overlord. Phitsanulok and Nakhon Sri Thamarat were listed among the eight great first-rank cities (Phraya maha nakhon). Mueang Sing, Mueang In and Mueang Phrom were downgraded to be the level of four cities (เมืองจัตวา) under Lopburi.
In 1455, Trailokkanat sent envoys to the Sultanate of Malacca. The Siamese had been suspicious of the sultanate since its conversion to Islam. The expedition was mentioned in Portuguese chronicles, written several years later, as not of great significance.
Wars with Lanna
Yuttittira – a Sukhothai royalty and Trailokkanat’s relative - was a close childhood friend of Trailokkanat. Trailokkanat himself promised him the title of Uparaja. However, after Trailokkanat’s reformes, Yuttittira ended up in the title of the Governor of Pichit. Yuttittira also claimed to be the rightful king of Sukhothai.
The Lanna kingdom under Tilokaraj was so powerful that he led armies down south to subjugate Ayutthaya. In 1456, Yuttittira sought Tilokaraj’s support and led Lanna armies to capture Sukhothai and proceeded further towards Ayutthaya. Trailokkanat, however, led Ayutthayan armies to successfully defeat the Lanna armies.
In 1461, Tilokarat and Yuttittira led the Lanna armies to invade Ayutthaya but without achieving fruitful results and retreated. Trailokkanat then took this opportunity to retake Sukhothai. Trailokkanat, upon seeing the seriousness of the wars, crowned himself as the king of Pitsanulok in 1463 – thus moving his base from Ayutthaya to Pitsanulok – to be able to cope with Lanna wars.
Trailokkanat, accompanied by more than 2,000 followers, was the first Siamese king to be ordained as a monk. The ordination took place at Wat Chula Manee in 1461.
In 1463, the Lanna invaded again. Trailokkanat sent his son, Prince Indraracha, to crush the invading armies. Indraracha defeated Yuttittira but was in turn killed during battles against Nagara – Tilokaraj’s uncle.
Lanna then, however, was plunged by her own internal princely conflicts. In 1474, Trailokkanat finally expelled the Lanna out of his kingdom. Next year, Tilokaraj sought peace settlements.
In Phitsanulok, Trailokkanat ordered the establishment of new temples, as well as the restoration of existing older ones. He ordered the construction a chedi and other buildings on the campus of Wat Ratchaburana, for example.
In 1485, Trailokkanat appointed his son Prince Chaiyachetta (later Ramathibodi II) as the Uparaja and King of Sukhothai. The title "King of Sukhothai" then became a title for Ayutthayan Crown Prince. However, upon Trailokkanat's death in 1488, his two sons inherited the two kingdoms, thus separating the union once again.
