"The Mosul Question (1918-1926)" is a scholarly book that addresses the complex dispute over the Mosul region between Great Britain and the Ottoman Empire, and later between Great Britain and Turkey. The analysis spans the years 1918 to 1926 and highlights the political, diplomatic, military, and legal dimensions of this conflict. The book emphasizes Great Britain's role as a leading member of the League of Nations at a time when Turkey was not even a member. The resolution of the Mosul question is considered a pivotal moment in the history of the Middle East, with effects that are still felt today. The conflicts in Iraq, particularly the First Iraq War and the Second Gulf War, illustrate the ongoing geopolitical tensions exacerbated by the region's rich oil resources. This book is aimed at students of International Relations and History, as well as anyone interested in the connections between history and international politics.
