Covering the period from 1878-1915, Ottomans and Armenians is a military history of the Ottoman army and the counterinsurgency campaigns it waged in the last days of the Ottoman empire. Although Ottomans were among the most active practitioners of counterinsurgency campaigning in the late-nineteenth and early-twentieth centuries, in the vast literature available on counterinsurgency in the early twenty-first century, there is very little scholarly analysis of how Ottomans reacted to insurgency and then went about counterinsurgency. This book presents the thesis that the Ottoman government developed an evolving, 35-year, empire-wide array of counterinsurgency practices that varied in scope and execution depending on the strategic importance of the affected provinces.
