Book excerpt: The fourth edition of Historical Dictionary of Turkey covers Ottoman Empire and the Republic of Turkey through a time span of more than six centuries. It presents the basic characteristics of the two periods and traces the developments from an empire to a state-nation, from tradition to modernity, from a sultanate to a republic, and from modest country to a country that is already a regional power and further aspiring becoming a country to be reckoned with. This is done through a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 900 cross-referenced entries on important personalities, politics, economy, foreign relations, religion, and culture. This book is an excellent resource for students, researchers, and anyone wanting to know more about Turkey.
