In 2001, Hilmar Kaiser published a ground breaking study for the first time highlighting the role of Armenians in the humanitarian resistance in Syria. In a seminal mono-graphic study on the Diarbekir region he showed how provincial authorities played a dynamic role in shaping the crime. He contributed for the Oxford Handbook of Genocide Studies the entry on the Armenian Genocide. Most recently, he analyzed Ottoman policies in the provinces of Van and Erzerum and the decision for genocide.
His numerous publications include “The Baghdad Railway and the Armenian Genocide, 1915-1916.
