This edited volume conceives of International Relations (IR) not as a unilateral project, but more as an intellectual platform. It is in this vein of thought that each contributor explores Islamic contributions to the field, addressing the theories and practices of the Islamic civilization and of Muslim societies with regards to international affairs and to the discipline of IR. The inclusion of Muslim contributions is not meant to create an isolationist, judicious divide between what is Islamic and what is not. Instead, this study supports the inclusion of that knowledge as a building block in the field of IR. An outcome of the Co-IRIS team (International Relations and Islamic Studies Research Cohort), this study draws together the combined expertise scholars of Islam in international affairs.
