Chetthathirat

Chetthathirat, also known as Borommaracha II, was a 17th-century king of Ayutthaya, ruling for less than a year before his execution. Born around 1613 as the eldest son of King Song Tham, he belonged to the Sukhothai dynasty. His brief reign, from December 1628 to 1629, was marked by court intrigue and ended when the nobleman Prasat Thong seized power and had him killed.

Today, Chetthathirat is remembered as a tragic figure, a young monarch whose youth and inexperience proved fatal in the brutal world of Siamese royal succession. His story, chronicled by the Dutch merchant Jeremias van Vliet, offers a window into the political turbulence of 17th-century Siam. [edit]

Chetthathirat was born circa 1613 in Phra Nakhon Si Ayutthaya, the capital of the Siamese kingdom. His father, King Song Tham, ruled Ayutthaya, and his mother was Queen Ammarit. As the eldest son, he was known in childhood as Chetthakuman, meaning "Chettha the Infant." He had two younger brothers, Athittayawong and Phra Sisin.

Growing up in the royal court, Chetthathirat was surrounded by the political machinations that defined Ayutthayan politics. His father's reign, which lasted from 1610 to 1628, was relatively stable, but tensions simmered beneath the surface. The young prince received the education typical of a royal heir, though details of his upbringing remain scarce.

His life changed abruptly when King Song Tham fell ill and died in 1628. On his deathbed, Song Tham conveyed his wishes through the influential royal page Okya Sri Vorawong, designating Chetthathirat as his successor. At around fifteen years old, Chetthathirat was thrust onto the throne, unprepared for the challenges that lay ahead. [edit]

Chetthathirat ascended to the throne on 12 December 1628, following his father's death. His reign, however, lasted less than a year. As a sixteen-year-old king, he faced immediate challenges from powerful court factions, including the ambitious nobleman Prasat Thong and the Japanese adventurer Yamada Nagamasa.

During his brief rule, Chetthathirat attempted to consolidate power, but his youth and inexperience left him vulnerable. In 1629, Prasat Thong orchestrated a coup, deposing and executing the young king at Wat Khok Phraya. His death paved the way for Prasat Thong to seize the throne, marking the end of the Sukhothai dynasty's hold on Ayutthaya and the beginning of the Prasat Thong dynasty.

His younger brother Athittayawong briefly succeeded him, reigning for about seven months (some sources say thirty-six days) before the council transferred power to Prasat Thong. Chetthathirat's reign, though short, is documented in the chronicles of Jeremias van Vliet, providing a rare glimpse into the turbulent politics of the era. [edit]

Chetthathirat is remembered as a tragic figure in Thai history, a young king who became a pawn in the deadly games of court intrigue. His story illustrates the brutal realities of royal succession in 17th-century Siam, where youth and inexperience were fatal liabilities.

Thai historical sources treat his reign as a brief transitional period between the Sukhothai dynasty and the Prasat Thong dynasty. His execution served as the pivotal event that enabled Prasat Thong's rise to power, and his brief rule is often overshadowed by the more consequential monarchs before and after him.

Despite his short time on the throne, his story has been preserved through the chronicles of Jeremias van Vliet, making it one of the better-documented brief reigns of the period. [edit]

Chetthathirat does not appear in iFANN's published rankings. The Global Fame Engine has evaluated his historical footprint, but as of August 2026 he holds no placement in the Global Top 1,000 or any Top-100 scope list. His fame is that of a footnote in the annals of Ayutthaya, a king whose entire reign lasted less than a year, chronicled primarily by a Dutch merchant and remembered mainly by historians of Siam.

No fandom exists for Chetthathirat, and no formal name has ever been documented for his admirers. He is not a figure who inspires birthday billboards or streaming campaigns; his audience is confined to readers of Thai history and students of royal succession. The only nod to popular culture is a YouTube historical drama, 'The Crown of Ayutthaya, Chapter 18: King Chetthathirat and King Athitwong,' which presents his story in an educational, not fan-driven, format.

In the ledger of global attention, Chetthathirat is a ghost, a name that surfaces in scholarly footnotes and niche historical forums, never in the broader currents of media coverage or public consciousness. His legacy is not measured in rankings but in the cautionary tale his brief life provides: a young king, a swift execution, and a dynasty's end.[edit]

Chetthathirat's childhood name, Chetthakuman, translates to "Chettha the Infant," a reflection of his youth within the royal family. His reign is sometimes listed as 1628–1630 in the Buddhist Era calendar, while Western sources typically cite 1628–1629. His successor, his nine-year-old brother Athittayawong, reigned for only about seven months before the council transferred the throne to Prasat Thong. His execution took place at Wat Khok Phraya in Ayutthaya. He is often confused with Setthathirat I of Lan Xang, a Lao king who lived a century earlier, due to the similarity of their names.

One of the most retold stories from his brief time on the throne is the manner of his death: he was executed at a young age, a victim of the nobleman Prasat Thong's ambition. The Dutch merchant Jeremias van Vliet, who was present in Ayutthaya, chronicled the young king's fall, and his account remains a primary source for historians. Another tale, perhaps apocryphal, claims that Chetthathirat's execution was carried out with a ceremonial sword, a detail that underscores the ritualized brutality of Siamese court politics. His body was reportedly left unburied for a time, a final indignity for a monarch who had reigned so briefly.[edit]

Chetthathirat was the eldest son of King Song Tham and Queen Ammarit. He had two younger brothers: Athittayawong, who briefly succeeded him, and Phra Sisin, also known as Phra Phanpi Sisin. The family belonged to the Sukhothai dynasty, a lineage tracing its roots to the ancient kingdom of Sukhothai.

Historical records do not document any marriages or children for Chetthathirat, who died at approximately sixteen years of age. His family's legacy was overshadowed by the political turmoil that followed his death, with his brother Athittayawong meeting a similar fate at the hands of Prasat Thong. [edit]

Chetthathirat's story is intertwined with several key figures of 17th-century Ayutthaya. His father, King Song Tham, set the stage for his succession. The nobleman Prasat Thong orchestrated his downfall and later founded a new dynasty. The Japanese adventurer Yamada Nagamasa was a rival at court. His younger brother Athittayawong briefly succeeded him. The Dutch merchant Jeremias van Vliet chronicled his reign, providing a rare historical record. [edit]

Historical records from 17th-century Siam do not document any romantic relationships, marriages, or offspring for Chetthathirat. Given that he was approximately 16 years old at the time of his death and his reign lasted less than a year amid intense political turmoil, no marriages or consorts are recorded in the available historical sources. His status at death was unmarried per available records. [edit]

The only modern tribute to the fallen monarch appears in a YouTube video titled "King Chai Chetthathirat | The Great King Who Disappeared in the Battlefield," a digital artifact keeping his name alive centuries later. This posthumous attention stands in stark contrast to the silence that surrounded his end in the Ayutthaya Kingdom, where royal chronicles recorded his passing around 1629. Historical accounts place his death within the capital's walls, marking the abrupt conclusion of a reign defined by court intrigue rather than military campaigns or public service. While some titles suggest a disappearance on the battlefield, no contemporary source confirms a specific cause like combat wounds or illness; the records simply note his execution following the seizure of power by the nobleman Prasat Thong.

The transition was swift and brutal, with the throne passing immediately to his brother Athittayawong, who ruled for a brief seven months before the council transferred authority to the new dynasty leader. Instead, the event was documented through the eyes of Dutch merchant Jeremias van Vliet, whose chronicles provide the primary window into the political turbulence that claimed the young king's life. His estate and kingdom were absorbed entirely by the succeeding regime, leaving no separate legacy of wealth or property to manage.[edit]

As a 17th-century monarch who reigned for less than a year and was executed at age 16, no modern net worth estimates exist for Chetthathirat. His estate would have been absorbed by the succeeding regime under Prasat Thong. The concept of celebrity net worth is not applicable to pre-modern monarchs, and no estate management or posthumous revenue streams exist for this historical figure. [edit]
