On this date in 1939, 18 junior officers of the Thai military were shot in Bangkok.

Ostensibly condemned for being part of a coup plot to depose the adolescent King Ananda Mahidol in favor of his abdicated predecessor Prajadhipok, they were in reality the casualties of a purge by the Field Marshal-turned-Prime Minister Phibun Songkhram.

It’s alternatively transliterated “Phibun Songkhram” or “Pibunsonggram”, and familiarly abbreviated to “Por”, but by any name he dominated Thai politics for a generation.

One of the military leaders of the bloodless 1932 Siamese Revolution that made the country a constitutional rather than an absolute monarchy, Phibun had in 1938 muscled his way to the Prime Ministership.

Beset by assassination attempts linked to royal revanchists to whose purposes the young turk’s programme was deeply inimical, Phibun determined to break the back of monarchism en route to a modernized, militaristic nationalism (pdf) that would be right at home in the imminent world war.*

As 1939 opens, we join the narrative of Paul Handley’s The King Never Smiles:

Phibun swept the capital and arrested 50 royals, nobles, and soldiers in the clique of his People’s Party rival Colonel Song Suradej for plotting his overthrow …

Whatever the truth behind the cabal, its quashing came to represent the final victory of the 1932 revolutionists and the constitutionalists over the monarchists. To mark it, Phibun commissioned a huge monument to the constitution, later called Democracy Monument, in the middle of the city’s main thoroughfare, Rajadamnoen (“royal progress”) Avenue.

The Democracy Monument in Bangkok.

The eighteen officers who took it in the shorts on this date were not joined by condemned VIPs like royal blood Prince Rangsit, who copped a commutation. It’s widely thought now that the “Songsuradet Rebellion” — or aptly-named “Rebellion of 18 Corpses” — was trumped-up, if not an phantasm altogether.

The Democracy Monument was not the only bulwark of Thai nationalism thrown up by Phibun in the year between the “conspirators'” January arrest and their deaths this day.**

He dropped the old absolutist name “Siam” in favor of the more nationalistic “Thailand” in June of that year; made the date of the 1932 revolution a national holiday; stripped the language of class-distinctive structures; and pressed irredentist claims against neighboring French colonies.

And if the royal house was efficiently marginalized by Phibun, it would yet develop in the latter part of the century into one of the region’s weightiest political entities† … intertwined with the Thai military Phibun helped hoist to pride of place, a formula that has left coups and unstable governments a presistent feature of the political landscape down to the present day.

* And subsequently, too. Despite aligning with the Axis powers during World War II, Phibun was a feted anti-Communist dictator as Washington started counting dominoes in Southeast Asia in the 1950’s.

** The Wikipedia page for the rebellion claims that the executions were carried out in batches of four per day. A New York Times report of December 6, 1939 said that all 18 had been executed the previous day.

† The current King Bhumibol Adulyadej, who coincidentally turns 81 today, is the world’s longest-reigning monarch as of this writing … with no shortage of concern about the conflict his passing may unstop.
