When the Ottomans commenced their modernizing reforms in the 1830s, they still ruled over a vast empire.In addition to today's Turkey, including Anatolia and Thrace, their power reached over Mesopotamia, North Africa, the Levant, the Balkans, and the Caucasus.The Sultanate was at the apex of a truly multi-ethnic society.Modernization not only brought market principles to the economy and more complex administrative controls as part of state power, but also new educational institutions as well as new ideologies.Thus new ideologies developed and nationalism emerged, which became a political reality when the Empire reached its end.This book compares the different intellectual atmospheres between the pre-republican and the republican periods and identifies the roots of republican authoritarianism in the intellectual heritage of the earlier period.
