Ivo Andrić, Serbian Nobel prize winner for literature, was also famous for his work in studying the Turkish historic sources, especially the Islamic religion and its influence on Bosnia. He dealt with this topic in his thesis The development of spiritual life in Bosnia under the influence of Turkish rule, which he presented in Graz in 1924. His thesis was presented in Austria, shortly after the ruin of Austro-Hungarian empire, at the time of forming the Kingdom of Yugoslavia, when Andrić was a young Yugoslav diplomat. As an intellectual and a writer from the Balkans, Andrić observed all of the important cultural features of the Eastern and Western civilizations. They were specifically opposed throughout the long Medieval period in the region of Balkan, and especially his homeland Bosnia.
