Is a law against denial really necessary? Facts are facts, and the facts of genocide speak for themselves.

The founding crime of the Turkish nation was genocide. A deliberate, and thoroughly effective genocide of Turkey’s indigenous Armenian Christians and a genocidal ethnic cleansing of Syrian Christians was carried out in 1915. The genocidal ethnic cleansing of Greek Christians peaked just after the First World War. These were genocides of forced marches, starvation, and Einsatzgruppen, not gas chambers. But they were directed from the highest level of the government, carried out by military and civilian officials, and they were thoroughly effective.
Taner Akçam’s The Young Turks’ Crime Against Humanity; The Armenian Genocide and Ethnic Cleansing in the Ottoman Empire is a landmark in genocide scholarship, and a fitting successor his two earlier books on the subject, his 2004 From Republic to Empire; Turkish Nationalism and the Armenian Genocide, and his 2006 The Armenian Genocide and the Question of Turkish Responsibility . Akçam’s goal in Crime Against Humanity is to refute the denialist claim that the only evidence of genocide comes from biased sources: Armenians and their Western supporters, and, therefore, that nothing has been proven. Some scholars have assumed that Turkish concealment and destruction of government records makes countering this argument directly impossible. Akçam used Ottoman files that do survive and are open to scholars to demonstrate that the deliberate and official nature of the “ethnic cleansing of the Ottoman Greeks and the genocidal policy against the Armenians can be demonstrated through these documents alone.” Case closed.
A Question of Genocide: Armenians and Turks at the End of the Ottoman Empire, (Oxford, 2011) is a different kind of book, the product of a ten-year series of meetings convened by historians from Turkish and Western universities to produce a shared understanding of the events of 1915. Among Turkish scholars willing to attend and to contribute chapters, “There was no dispute that deportations and massacres had occurred, that the forced movement of the Armenians had been ordered by the Young Turk government, that the mass killing was the result of both government and party actions, and that while there were several moments of Armenian resistance (most notably at Van), there was no civil war. The two opposing nationalist narratives were replaced by a single shared account based on evidence.”
These two books settle the debate over whether the events of 1915 were a deliberate, officially ordered genocide for everyone except politically inspired denialists and members of the Flat Earth Society.
