As a result of the Arab uprisings and especially the Syrian crisis, Lebanon is experiencing a radicalization of its religious communities. This radicalization is not only evident in the Muslim community, where militant Islamism and Salafism are on the rise and Sunni-Shia conflicts are becoming more and more violent; the Christian community and especially the Maronites are also showing forms of radicalization, asserts Maximilian Felsch, who conceptualizes this trend as ‘Christian nationalism’. Olivier Moos spoke with Dr Felsch in Beirut about this issue.
