What happened to the Armenians of Western Armenia who remained in the Ottoman Empire in 1915? What state policy has Turkey pursued towards them? How did it happen that after 1920 the Soviet Union studied the Kars and Sevres Treaties and seriously discussed the issue of the return of Kars and Ardahan from Turkey? A book that was awaited especially by those who noticed the active work of Turkish historians in the archives. In the archives, where you can find documents and information about the Genocide of Armenians survivors. Two Armenian Turkologists worked in detail and thoroughly in the archives. Why and how they decided, came and stayed: the Armenians of Western Armenia and their descendants tell in this book. This book, first of all, is a very important testimony for Western Armenia, and the publication of such a book is welcomed. Thank you for the work thanks to which this book was published.
