This study investigates the causes beneath the absence of non-Western theorizing efforts in the field of International Relations (IR), aiming to shed light on intellectually and politically defectiveness of the Arab World in the field, as manifested since the outbreak of the Arab Spring revolutions. To this end, the study discusses the position of the Arab World in IR and illustrates how the North (the Centre) deliberately ignores knowledge production on international relations from the South (the Periphery) through abstraction, reductionism, and exclusion. Finally, the study scrutinizes how the situation in the Arab World reflects the continuation of colonialism in two evident forms: epistemologically through the knowledge-power nexus; and by subjugation or keeping states, even those that are nominally independent, subservient to the Great Powers in international politics.
