Peace Education encompasses a diversity of pedagogical approaches within formal curricula in schools and universities and non-formal popular education projects implemented by local, regional and international organizations. It aims to cultivate the knowledge and practices of a culture of peace. In Lebanon, this culture has mainly been promoted since the late 1990s by non-governmental organizations, engaged intellectuals and artists. Additionally, grassroots student dialogue clubs have flourished in a number of secondary schools. However, in the university context, it is considered a rare phenomenon. This paper first introduces the issue of Peace Education in Lebanon. It then presents the conceptual characteristics and examples of applications of a Peace Education approach I developed and adopted in my classrooms from 2007 to 2014 at three universities (St Josef University of Beirut, Notre Dame University and Holy Spirit University) with three thousand students of different religious, cultural, socio-economic and political backgrounds. In conclusion, it identifies the positive changes the various class activities produced in students’ perceptions and relationships, and the obstacles that this approach faced in a context of continuous physical and psychological war.
