Since the beginning of the Syrian uprising in Spring 2011, the social, economic and political Lebanese landscape - described as one of the most unstable and fragile of the Middle East - has unexpectedly showed a great ability in absorbing the effects of the crisis. The massive influx of Syrian refugees and the prolonged status of war in Syria have indeed exacerbated the pre-existent domestic political and sectarian tensions in various Lebanese regions. But the country appears far from being on the brink of a new nationwide 'civil war'. This paper intends to discuss the exceptional flexibility of the Lebanese system in the light of its modern and contemporary history and to examine the crucial role played by local actors in the current transition.
