This study explores Iran’s political and cultural history in order to better understand the country’s current stance on international politics and peace. This study asks: what defines peace in Iranian discourse? To this end, this thesis employs a Foucauldian archaeological and genealogical methodology on historical research and contemporary primary sources. The historical data is mainly secondary sources, whilst primary sources are drawn from contemporary speeches, interviews and articles presenting Iranian foreign political thought. First of all, this study uncovers the major research gaps concerning Iran in peace research. This speaks to the general lack of diversity and inclusiveness in the subject of Peace and Conflict studies, which is contrary to its claim of being universally relevant. Relevance comes with knowledge of other traditions and conversations across divides, which is typically absent in a universalised provincialism. Secondly, contemporary Iranian political discourse represents a continuity from antiquity, incorporating deep-rooted practises of cosmopolitanism and structural peace, represented by 4000-years of experiences in state-building, conflict management, continuous movement of people and changing centres of political power. In short, Iran has a long experience of multi-polarity, multi-ethnicity and multi-religiosity across time and space.
