The sectarian structure of the Lebanese political system has contributed to periods of sectarian violence and wars over the past four decades. This article highlights the origin of sectarianism in Lebanon and discusses how public and religious schools in the country have reinforced sectarian divisions in the Lebanese society. This is a conceptual article showing that the existing poor educational policies and approaches have de-emphasized national identity and permitted the establishment of religiously segregated schools leading to the growth of sectarian divisions among the Lebanese communities. Better educational approaches are thus necessary for the creation of responsible and socially aware citizens, as well as a culture of tolerance within the country. The article proposes educational reforms, such as the greater implementation of citizenship education, the diversification of school communities, and the promotion of interaction among students from different religious backgrounds as an effective strategy that can build social cohesion and reduce future sectarian violence in Lebanon. As Lebanon is highly susceptible to regional and internal political crises, a long-term educational strategy must be developed to protect children from future hazards of sectarian hatred and violence.
