Armenian genocide denial
In the aftermath of the Armenian Genocide, the newly founded Republic of Turkey created an organization that investigated how many Armenians had died between 1915 and 1918. It was discovered that 800.000 people had died during this time, though many historians believe the death toll is much higher. The founder of modern Turkey, Mustafa Kemal Atatürk, admitted to the killing of Armenians more than once after the First World War, and many within his movement agreed accountability was needed. This changed in the following years, when it was discovered that many of Turkey's founders were involved in the genocide. Since these men were celebrated as heroes during the First World War, their crimes were not recognized by Turkey.
