The Curse of the Sailendra Dynasty


 

Sometimes, when the moon hangs low over the rice paddies of Central Java like a dead man’s eye, the old-timers will tell you about the curse that fell upon the Sailendra dynasty. They’ll tell you about kings who died in months instead of years, about power that corrupted and consumed, about a kingdom that bled itself white from the inside out.

For two hundred years—two long centuries—the Sailendra had ruled over Java like feudal gods, their greatest achievement that magnificent stone mountain called Borobudur, rising from the earth like some Buddhist fever dream. But power, as any small-town politician will tell you, has a way of eating its own tail.

The Dying Time

The trouble started after King Rakai Kayuwangi Dyah Lokapala went to meet whatever gods waited for dead kings. The Wanua Tengah III inscription, carved in stone in 908 AD like an obituary that would outlast the pyramids, tells the story with the cold precision of a coroner’s report.

The Sailendra dynasty didn’t just fall—it imploded. Like a house of cards in a hurricane, like a marriage built on lies, like everything good that turns rotten when you’re not looking.

What followed was the kind of political nightmare that would make even the most bloodthirsty Game of Thrones fan queasy. Kings rose and fell like mayflies, their reigns measured not in years but in heartbeats. Dyah Tagwas managed to keep his crown for exactly six months before something—or someone—cut his story short. Dyah Dewendra? Five months. Hell, poor Rakai Gurunwangi Dyahbhadra lasted exactly one month, probably spent most of it figuring out how to pronounce his own name.

The scholar Kusen, writing in 1994 (and probably never imagining his academic work would be retold like a ghost story), documented this parade of doomed rulers with the methodical care of a man cataloging disaster. Only Rakai Watuhumalang Dyah Jebang managed to hang on for four years, which in that political climate was practically a lifetime achievement.

The Dawn Breaks

But here’s the thing about darkness—it always makes the light seem brighter when it finally comes. And in Java, circa 899 AD, that light had a name: Rakai Watukura Dyah Balitung.

Now, Balitung wasn’t supposed to be anybody special. He came from Watukura, way out in the sticks near what’s now Purworejo—the kind of place where nothing ever happens except the same damn thing, day after day. While the power brokers were busy murdering each other in the halls of Kedu-Prambanan, Balitung was probably learning statecraft from the bottom up, watching and waiting like a spider in its web.

The man had what every successful politician needs: patience, cunning, and the good sense to marry well. He wed the daughter of Rakai Watuhumalang Dyah Jebang, that four-year survivor, making himself a son-in-law prince with just enough legitimacy to make his play for the throne.

The historian B.J.O. Schrieke (writing in 2016, long after the dust had settled on these ancient ambitions) compared Balitung to two other Indonesian princes who clawed their way to power through marriage rather than birthright: Airlangga from the 11th century and Raden Wijaya, who founded Majapahit. Schrieke called it “matrilineal succession,” but I call it what it was—three smart men who understood that sometimes the best way to the throne is through the bedroom.

The Inscription King

When Balitung finally took the crown in 899 AD, he didn’t just rule—he documented. Thirty-seven inscriptions, carved in stone like a man trying to write himself into history with a chisel. More than any other ruler of the Ancient Mataram Kingdom, because when you’re not born to the throne, you’ve got to work twice as hard to convince everyone you belong there.

It’s like those small-town mayors who plaster their names on every park bench and street sign—except Balitung’s inscriptions were carved in stone and scattered across Java like a political calling card that would last a thousand years.

The Mantyasih inscription told the story of his marriage, his claim to legitimacy. The Wanua Tengah III inscription listed all the kings who came before, a complete genealogy that read like a medieval phone book. But funny thing—some names appeared in one inscription but not the other, particularly the long-reigning kings. According to Kusen, this wasn’t an accident. Balitung was crafting his own narrative, emphasizing his marriage connection while downplaying the successful rulers who might make his own claim look weak.

The Great Expansion

But legitimacy was just the beginning. Balitung looked around at the old kingdom—the Kedu-Prambanan valley where Javanese civilization had flourished for centuries—and saw what any good leader sees: a population growing too big for its britches, people packed in like sardines while vast stretches of Java remained wild and unclaimed.

The solution was as old as human ambition: expand or die.

Under Balitung’s rule, the Ancient Mataram Kingdom spread like spilled ink across Java’s map. North to Mount Sindoro-Sumbing and the Dieng plateau, west toward the Sunda-Galuh border, south to develop the coastal regions around present-day Kebumen, Purbalingga, and Cilacap. The scholar Baskoro Daru Tjahjono, writing in 2008, described it as the remnants of the kingdom spreading to “various corners of Java”—but I think he was being modest. This wasn’t just expansion; it was conquest disguised as settlement.

The Eastern Gambit

The most audacious move was Balitung’s push into eastern Java, where the Kanjuruhan Kingdom had been minding its own business for generations. The Kubu-kubu inscription from 905 AD tells the story with the bureaucratic precision of a tax document, but read between the lines and you can see the real story: Balitung sent his officials to “conquer the Bantan area,” and suddenly the rulers of Kanjuruhan found themselves bowing to a new master.

The scholar Galih Abi Khakam, writing his thesis in 2014, noted that one of the officials mentioned in the inscription was called “Rakai Kanuruhan”—literally “the lord of Kanjuruhan.” In other words, Balitung had turned the local rulers into his vassals, probably through a combination of political pressure, economic incentives, and the implied threat of military action.

Soon, Balitung’s inscriptions were popping up all over East Java—Mojokerto, Malang, Lamongan—like a medieval version of franchise expansion. Some of those inscriptions were so impressive that the Majapahit rulers, centuries later, had them recopied, probably thinking, “Now that’s how you project power.”

The Legacy

In the end, Balitung did what every successful politician dreams of: he took a dying kingdom and made it bigger, stronger, and more influential than it had ever been. He proved that sometimes the best leaders come from the margins, that legitimacy can be earned as well as inherited, and that the right marriage can be worth more than the right bloodline.

But mostly, he proved that in the game of thrones—whether in medieval Java or modern Washington—the players who think ten moves ahead are the ones who survive to carve their names in stone.

And in the quiet hours before dawn, when the mist rises from the rice paddies and the old stones whisper their ancient secrets, you can almost hear the ghost of Balitung laughing at the kings who thought power was their birthright, never realizing that sometimes the most dangerous man in the room is the one nobody sees coming.
