The fall of the Ottoman Empire during World War One and the emergence of the modern state system in the Middle East have received significant attention in academic literature. However, the impacts that the proliferation of state borders in the 19th and 20th centuries have had on political and economic integration within the Middle East is often ignored. This study argues that between the mid-19th and mid-20th centuries the region underwent significant structural changes. Furthermore, these changes were driven by external intervention and internal decline. A number of theoretical assumptions are posited concerning the importance on integration and cooperation of the following: the increase in borders and claims to sovereignty and the separation of peoples/markets. The conclusions drawn are that the change from a system characterised by large political actors and integrated markets to one which is characterised by smaller states and separated markets led to the disintegration of the region's internal relations
