Every March 15, Armenian communities across the United States, Europe, Latin America, and the Middle East gather for ceremonies, lectures, monument unveilings, and memorial services honoring one man and one mission: Soghomon Tehlirian and Operation Nemesis.

By William Paparian

On that day in 1921, 25-year-old Armenian survivor Tehlirian walked up behind Talaat Pasha, the chief architect of the 1915 Armenian Genocide, in broad daylight on a Berlin street and shot him in the head. The act was not random vengeance. It was the most visible strike in a secret Armenian Revolutionary Federation (ARF) campaign called Operation Nemesis, launched because the world had failed to deliver justice. For the Armenian diaspora, March 15 is “Avenger’s Day,” an annual remembrance established by the ARF in 1974. It is more than nostalgia; it is a living affirmation of identity, moral resolve, and the refusal to let genocide go unpunished.

The Shadow of Genocide

The date carries profound weight because of its history. Between 1915 and 1923, the Ottoman Young Turk government orchestrated the systematic deportation, massacre, and death marches of roughly 1.5 million Armenians. After World War I, promises of tribunals faded. Key perpetrators, Talaat Pasha, Enver Pasha, Cemal Pasha, escaped into exile, living freely while survivors rebuilt shattered lives in foreign lands. International justice had failed.

In response, the ARF’s 1919 congress in Yerevan authorized Operation Nemesis: a secret mission to deliver accountability where none existed. Named for the goddess of retribution, it targeted those most responsible. Between 1920 and 1922, the group carried out at least seven successful assassinations across Europe and the Middle East.

Tehlirian: Survivor and Avenger

Tehlirian became the face of that campaign. A genocide survivor who had lost his mother, sisters, and most of his family on the death marches, he was chosen to target Talaat, whom Shahan Natalie called “Number One.” After months of surveillance in Berlin, Tehlirian pulled the trigger on March 15, 1921. He did not flee; he waited to be arrested.

At his two-day trial in June, the courtroom became an unofficial tribunal on the Genocide. Survivor testimony, expert witnesses, and Tehlirian’s calm statement, “I have killed a man, but I am not a murderer,” filled the German press. The jury acquitted him in less than an hour. The verdict sent shock waves: a European court had implicitly recognized the Armenian Genocide as a mitigating circumstance for an act that would otherwise have been simple murder.

Diaspora Memory and Identity

For the diaspora, this sequence, genocide, impunity, targeted justice, public vindication, condenses the 20th-century Armenian experience into one dramatic episode. Most diaspora families trace their presence in California, France, Argentina, or Lebanon directly to genocide survivors who arrived as refugees. Annual April 24 commemorations remember the victims; March 15 remembers the response. It affirms that Armenians were not passive martyrs but agents who reclaimed agency when governments abandoned them. The act restored dignity and pride.

This truth resonates in my own family. My mother, Serpouhi, survived the horrors, and I grew up hearing fragments of the Dickranian family story—not as dramatic tales, but as quiet, enduring truths. Eventually, they found safety in America and rebuilt a life of quiet strength. Those stories shaped me—not with anger, but with a deep responsibility to remember and honor those who ensured our survival.

In Fresno, California, at the Masis Ararat Armenian Cemetery, a monument honors Tehlirian: an obelisk topped with a gold-plated eagle slaying a snake, symbolizing Armenian justice striking down Talaat Pasha, the “snake” as the chief architect of the Genocide. Erected in 1969, it remains a powerful pilgrimage site, drawing visitors who lay flowers and reflect on the enduring legacy of retribution and resilience.

Lessons for Today

The remembrance also looks forward. Turkey’s continued denial of the Genocide, coupled with recent threats against the Republic of Armenia, keeps the memory urgent. March 15 is not merely historical; it is a reminder that justice sometimes requires extraordinary measures when lawful avenues are closed. It inspires advocacy for recognition, reparations, and security, while also encouraging reflection: many Armenians today distinguish between the justified retribution of 1921 and modern violence, using the anniversary to explore non-violent strategies for the 21st century.

Ultimately, the Armenian diaspora remembers Soghomon Tehlirian and Operation Nemesis every March 15 because the date captures the central narrative of our collective identity: a people who survived attempted extermination, refused to accept impunity, and acted when the world would not. Tehlirian’s bullet in Berlin did not erase the Genocide, but it ensured its chief architect did not enjoy a quiet exile—and that Armenians would never forget they once delivered justice with their own hands. For millions in the diaspora—including me, carrying forward my mother Serpouhi’s legacy, March 15 is the day we reaffirm that memory, that pride, and our unbreakable commitment to “never again.”
