Introducing new evidence from more than 600 secret Ottoman documents, this book demonstrates in unprecedented detail that the Armenian Genocide and the expulsion of Greeks from the late Ottoman Empire resulted from an official effort to rid the empire of its Christian subjects. Presenting these previously inaccessible documents along with expert context and analysis, Taner Akçam's most authoritative work to date goes deep inside the bureaucratic machinery of Ottoman Turkey to show how a dying empire embraced genocide and ethnic cleansing. Although the deportation and killing of Armenians was internationally condemned in 1915 as a "crime against humanity and civilization," the Ottoman government initiated a policy of denial that is still maintained by the Turkish Republic. The case for Turkey's "official history" rests on documents from the Ottoman imperial archives, to which access has been heavily restricted until recently. It is this very source that Akçam now uses to overturn the official narrative.
