Peace Studies and Conflict Management most appropriately captures the contents of this book. The book espouses the relationship between international relations and peace and conflict studies with regards to origins, meaning and scope. Johan Galtung is said to be the father of Peace and Conflict Studies because of his numerous contributions such as the Conflict Triangle and Positive and Negative Peace etc. These issues were adequately captured. The factors that promote successful negotiation and the totality of Conflict resolution Mechanism were also discussed. This book delineates international conflicts and illuminates the interplay between power and collective security as substantive sources and responses respectively. Although there are many sources of international conflicts but power tussle or power struggle which encompasses the quest to acquire, preserve and consolidate power are the major source or causal factor of international conflicts. It manifested in classical wars such as the Greco Persian War, Peloponnesian War, Punic Wars, Thirty Years War etc.
