Yet what the president of the Unites States say or does not say, primarily for present-day political reasons, should not change what Armenians know and how they commemorate their own history.

And thankfully there are multiple other imaginative commemorations by different Armenians that will inform the general public about this black historical episode. They are a reminder that there is no monolithic “Armenian diaspora,” but more than six million Armenians descended from the Ottoman Armenians of 1915, each with their own family history.

These are people who call what happened to their grandparents and great-grandparents the Armenian Genocide but who are less exercised by the politics of it.

The centenary is the occasion for the publication of a wave of memoirs telling the terrible vivid stories of Armenian survivors. One, Fragments of a Lost Homeland tells the story of an entire family, the Didilians. Two more, Four Years in the Mountains of Kurdistan and Goodbye Antoura are moving childhood memoirs of Armenian survivors of 1915. These human stories are worth a hundred press-releases by lobbying groups.

A more technologically advanced example of the same phenomenon is the 100 Lives project, a website of films and stories launched by the two Armenian entrepreneurs Ruben Vardanian and Noubar Afeyan. The Armenians who are recorded here are less defined by victimhood than celebrated for how they survived and what they have achieved. The website even has, Buzzfeed-style, an item on “24 unusual ways to commemorate the genocide centennial.”

In the same spirit, the intrepid Armenian photographer Scout Tufankjian, formerly Barack Obama’s campaign photographer, is producing a book about the Armenian diaspora from Argentina to Ethiopia.

Armenians are also commemorating the tragedy in the lands where it actually happened in what is now eastern Turkey. Ara Sarafian from the London-based Gomidas Institute led a tour across eastern Turkey. In the town of Bitlis he has helped win approval for a new William Saroyan Street, named after the American-Armenian writer whose family came from the town.

In the Kurdish-majority city of Diyarbakir, where the Kurdish HDP political party has gone further than any other force in Turkey in reaching out to the Armenians, the Istanbul-born Armenian pianist Raffi Bedrosyan will play a concert on April 24 in the restored Armenian church.

In Istanbul itself there will be a commemoration event on the evening of April 24 in the center of the city in Taksim Square. The Turkish government, having soured the atmosphere by scheduling competing commemorations for the Battle of Gallipoli on the same day, is somewhat correcting its mistake by helping to hold a ceremony at the Armenian Patriarchate.

It adds up to a diverse commemoration of this awful historical event that highlights Armenian creativity even as it mourns the dead of 1915.
