Abstract

In the 17th century, the Ottoman State began to feel its being unable to follow the developments in Europe and to keep up with the changing world order. Following the glorious years of the Ottoman Empire, solutions were presented from various circles upon the dissolution in the state order, the situation of the people and the reasons for all these. The first known of these solutions is the Kochi Bey Treatises presented to two different and successive sultans. Kochi Bey, who predicted that the course of history had been changing in the 17th century, prepared a treatise / report with scientific-political-military-social content that was unprecedented in the Ottoman Empire before. He presented his treatises to Murat IV and his brother Ibrahim I. Although many studies have been conducted on the historical value and importance of the Kochi Bey treatises, we have tried to deal with the differences between the Kochi Bey treatises in a multifaceted way. The treatises were presented to the Sultan in two different characters. We aimed at revealing their differences in terms of style, content and purpose. When we compared the two treatises through the text critial method, we came accross two very different styles and contents of treatises. As required by the time and addressee, Kochi Bey has allowed us to witness to a period through these treatises between which the differences seem obvious. Our study aims to make this testimony obvious through the comparison of the two treatises.
