In the arguments concerning the modern history of the Ottoman Empire and the rule of Sultan Abdulhamid II, the second decade of his reign has been often neglected. Although this period was uneventful, we can find there several factors which would be important to understand Abdulhamid's rule as a whole. In analyzing this period the author pays attention to "the Ertugrul Mission (1889-1890)". Relying upon the Turkish Naval Archives she amalyzes this event and concludes the following about the second decade of Abdulhamid II's reign : (1)Abdulhamid II confirmed his autocracy, and its influence on Ottoman governmental activity was important. (2)Abdulhamid's foreign policy changed. While the relationship with Great Britain got worse, Turkey took the first step to wards pro-Germany diplomacy. (3)Economic semi-colonization was inevitable. Under budgetary deficits, the realization of state activities became very difficult. (4)The weekness of state power and the lost of British cooperation invited the decline of the Ottoman Navy. And the inability of self-defence became one of the reasons why Turkey depended on Germany from that time on.
