On April 24th, 2015 people around the world commemorated the centenary of the death of over one million Armenians. In their eyes, and in those of many around the world, they will be remembering a genocide perpetrated by the Ottoman Empire. Turkey has always explained the dead as simply victims of a vicious civil war, and continues to this day to refuse to acknowledge the events as constituting genocide. This argument has become, in turn, an international issue. Twenty national parliaments in democratic countries have voted to recognize the genocide, but Britain and the United States continue to equivocate for fear, it would seem, of alienating their NATO ally. In this seminal book, Geoffrey Robertson QC, a former UN appeals judge, sets out to prove beyond all reasonable doubt that the massacres and deportations were a crime against humanity which amounted to genocide.
