Beware the Ides of March: Caesar, Brutus, and the Filipino Betrayal That Still Haunts Us
"Et tu, Brute?" On the day the world remembers history's most famous betrayal, we examine the Filipino parallel that cuts even deeper — the execution of Andres Bonifacio at the hands of the revolution he built.
March 15. The Ides of March. In the ancient Roman calendar, the Ides simply marked the full moon — the midpoint of the month, a day for settling debts and honoring Jupiter. There was nothing inherently ominous about it.
Until 44 BC. And for Filipinos, the date carries a parallel betrayal — one that happened not on the steps of a Roman senate, but on a mountain in Cavite, 1,940 years later. Two revolutions. Two founding fathers. Two men who were elevated, then destroyed, by those they trusted most.
💡 Did You Know?
The Filipino-American community in Vallejo, CA — where PinoyBuilt is rooted — is one of the oldest and most established in California. Vallejo's Filipino population traces back to the early 1900s when Filipino workers arrived at the Mare Island Naval Shipyard. Today, an estimated 20–25% of Vallejo residents have Filipino heritage, making it one of the most Filipino cities in America.
Every Ides of March, Filipino history teachers in Bay Area schools quietly note that the Philippines has its own version of this story — and that it matters far more to us than Shakespeare ever did.
🇵🇭 Tagalog Word of the Day
Kataksilan
kah-tak-SIH-lan
Meaning: Betrayal; treachery; treason.
From the root word taksil (traitor). In Filipino culture, kataksilan carries a weight beyond simple disloyalty — it implies a violation of utang na loob (debt of gratitude), the deepest moral bond between people. To betray someone who elevated you is considered among the gravest offenses in Filipino ethics. The story of Bonifacio and Aguinaldo is, for many Filipinos, the original kataksilan.
"Beware the Ides of March"
On March 15, 44 BC, Julius Caesar — dictator of Rome, conqueror of Gaul, the most powerful man in the Western world — walked into the Senate at the Theatre of Pompey and never walked out. A group of approximately 60 senators, led by Marcus Junius Brutus and Gaius Cassius Longinus, surrounded him and stabbed him 23 times. Caesar fought back at first. But when he saw Brutus — his protégé, the man he had personally pardoned after the civil war — among the assassins, he reportedly pulled his toga over his face and stopped resisting.
According to some ancient accounts, his last words were not Shakespeare's famous Latin but Greek: "Kai su, teknon?" — "You too, my child?"
The betrayal is the point. Not the politics, not the daggers, not the 23 wounds. The betrayal. The man who owed Caesar his life was the one who helped take it. For nearly two thousand years, the Ides of March has been shorthand for the deepest kind of treachery — not an attack by enemies, but a knife from inside the circle of trust.
For Filipinos, that story should sound terrifyingly familiar.
Caesar and Brutus, Bonifacio and Aguinaldo
The parallel is almost too precise to be coincidence — if you believe in the cruel poetry of history.
The parallels are structural, not superficial. In both cases, the betrayal came from inside the house. In both cases, the men who wielded the daggers claimed they were saving the republic. In both cases, the republic they claimed to defend was destroyed anyway — by the very instability their betrayal created.
The Supremo: Andres Bonifacio and the Revolution He Built
To understand the weight of what happened, you have to understand who Andres Bonifacio was — and what he represented.
Born in Tondo, Manila to a working-class family. Orphaned young, self-educated, worked as a messenger and warehouse keeper. In July 1892, after Jose Rizal was arrested by the Spanish, Bonifacio co-founded the Katipunan — a secret revolutionary society that used Masonic rituals, mutual aid, and mass education to recruit members. By 1896, it had over 30,000 members. Bonifacio proclaimed Philippine independence on August 23, 1896, and led the first armed uprising against Spain.
Bonifacio was not of the principalía — the landed Filipino elite. He was from the masses. A man of Tondo, not Kawit. He read Rizal's novels, French revolutionary texts, and Hugo's Les Misérables. He believed in a revolution of the people, not just for them. He insisted, at the Tejeros Convention, that whoever was elected should be recognized "regardless of his social condition and education."
That insistence would cost him his life.
Tejeros: The Convention That Became an Ambush
By early 1897, the revolution was in trouble. The Spanish had regrouped under Governor General Camilo de Polavieja, and the Katipunan in Cavite had splintered into two hostile factions: the Magdiwang (allied with Bonifacio) and the Magdalo (led by the Aguinaldo family's network in Kawit). The factions refused to help each other even while the Spanish recaptured town after town.
On March 22, 1897, leaders from both factions gathered at the estate house of Tejeros in San Francisco de Malabon (now General Trias), Cavite. The original purpose was to discuss defense strategy against the advancing Spanish. Instead, the meeting turned into an election for the leadership of a new revolutionary government.
Bonifacio chaired the assembly and swore to uphold the majority's decision. But the Magdalo faction held the numbers. Aguinaldo — who was not even present, as he was commanding troops against the Spanish at Salitran — was elected president. Bonifacio lost the presidency and the vice presidency. He was elected Director of the Interior, a lesser cabinet post.
Then came the insult that broke everything. Daniel Tirona, a Magdalo partisan, stood and declared that Bonifacio was unfit for even the Interior post because he was not a lawyer. In that single moment, the class divide between the Cavite elite and the Tondo revolutionary was laid bare for the entire assembly. Bonifacio, humiliated, drew his pistol. He declared the results null and void and dissolved the convention.
He never held power again.

In Defense of Aguinaldo: The Case History Rarely Makes
I grew up vilifying Emilio Aguinaldo. Many of us did. The man who murdered the Supremo. The Filipino Brutus. The traitor who sold out the revolution — first to the Katipunan's founder, then arguably to the Americans at Biak-na-Bato and beyond.
But history, when examined honestly, is rarely a story of pure heroes and pure villains. And if we are to truly understand the Ides of March — Roman or Filipino — we have to at least hear the defense, even if we don't accept it.
The Wartime Necessity Argument
In 1897, the Philippine Revolution was fighting for its life against Spain. The Katipunan was fracturing. Bonifacio, after Tejeros, had set up a rival government and was consolidating forces through the Naic Military Agreement — essentially calling for Aguinaldo's removal. From a purely military standpoint, two competing revolutionary governments fighting each other while the Spanish closed in was an existential threat. Aguinaldo's defenders argue that eliminating the rival government was brutal but necessary to prevent total collapse.
The Legal Process Argument
Aguinaldo did not personally execute Bonifacio. A military court — the Consejo de Guerra — tried the Bonifacio brothers and sentenced them to death on charges of treason and sedition. The court was convened by General Mariano Noriel, who had previously been a Bonifacio loyalist. Whatever its flaws, there was a trial. There was a defense lawyer. There were specific charges and witness testimony.
The Commutation Claim
In documents written decades later, Aguinaldo claimed that he initially commuted the death sentence to exile. He said he was pressured to reverse the commutation by his own Council of War — a group that included not only his allies but several former Bonifacio supporters, including Generals Noriel, Pio del Pilar, and Severino de las Alas. If Aguinaldo's account is accurate, the execution was not the act of a single tyrant but the collective decision of a revolutionary government under siege.
So Does the Defense Hold?
Partially. The context was real. The military threat was real. But the execution of the defense falls apart on the specifics: a jury stacked with Aguinaldo's men, a defense lawyer who acted as a prosecutor, a key witness allegedly bribed and threatened into testifying, a commander's wife reportedly assaulted during the arrest, and a commutation that conveniently never reached the executioner.
The wartime necessity argument might explain why Aguinaldo needed to neutralize Bonifacio. It does not explain why he needed to kill him. Exile, imprisonment, even house arrest — all were options. The Spanish were the enemy. Not the Supremo.
As Mabini wrote: the execution was the first time personal ambition defeated true patriotism in the revolution. And that verdict has proven far more durable than any of Aguinaldo's justifications.
The Deeper Parallel: Why the Betrayal Failed in Both Cases
The most devastating irony of the Ides of March — both the Roman and the Filipino version — is that the betrayal accomplished the opposite of its stated purpose.
Brutus killed Caesar to save the Roman Republic. Instead, he triggered a civil war that destroyed it. Caesar's adopted heir Octavian rose from the ashes and became Augustus — Rome's first emperor. The Republic was gone forever. Brutus, haunted and defeated, fell on his own sword at Philippi.
Aguinaldo eliminated Bonifacio to unify the revolution. Instead, he demoralized rebel forces across Manila, Laguna, and Batangas, who quit fighting. Emilio Jacinto and Macario Sakay — Bonifacio's closest allies — never recognized Aguinaldo's authority. The revolution fractured further, leading to the Pact of Biak-na-Bato, Aguinaldo's exile to Hong Kong, and ultimately, the arrival of the Americans — who replaced one colonial master with another.
In both cases, the betrayers claimed to serve a higher cause. In both cases, they served only themselves — and destroyed the very thing they claimed to protect.
Why This Matters to the Filipino Diaspora
We are 12 million strong in the diaspora. We carry the weight of this history even when we don't know its details. The Bonifacio-Aguinaldo wound is not ancient — it is alive in every Filipino community where factionalism, crab mentality, and the instinct to tear down our own leaders echoes the dynamics of Tejeros.
The Filipino political landscape — from the Marcos-Aquino divide to the Duterte-Marcos rupture — is still marked by the same patterns: inner-circle betrayal, personality politics over principle, and the willingness to destroy a movement rather than share power within it.
Bonifacio once said: "Matataas na tao ang dapat nating kalaban at ibagsak." — "It is the powerful who we must oppose and overthrow." He was talking about the Spanish. But the tragedy of Filipino history is that his own powerful allies applied the same logic to him.
Shakespeare gave Brutus the famous line: "Not that I loved Caesar less, but that I loved Rome more." Aguinaldo's defenders might say the same — that he loved the revolution more than the revolutionary. But the record suggests otherwise. And the Filipino people, like the Roman citizens who turned against the conspirators, have rendered their verdict across the centuries.
Bonifacio Day is November 30 — a national holiday. Aguinaldo's birthday, March 22 — the very date of the Tejeros Convention — passes without national observance. History remembers.
Beware the Ides of March.
Beware the men who kill their founders and call it patriotism.
And never forget the Supremo who believed the revolution belonged to all of us — not just the principalía.
Mabuhay ka, Supremo. Hindi ka namin makakalimutan.
💡 Did You Know? — The Fil-Am Connection
The San Francisco Bay Area is home to over 350,000 Filipino Americans — one of the largest concentrations of the diaspora in the United States. Vallejo alone is estimated to be 20–25% Filipino, with roots going back to the early 20th century Mare Island Naval Shipyard workforce. Daly City, just south of San Francisco, is often called the "Fil-Am capital of the US."
In Filipino-American households across the Bay Area, the story of Andres Bonifacio is passed down not just as history, but as a cautionary tale — a reminder that the greatest threats to any community rarely come from outside. Tejeros happened in a provincial estate in Cavite. Its lesson lives in every Filipino bayanihan circle where ambition quietly outpaces solidarity.
