Since Lebanon’s independence in the mid-1940s, its military—the Lebanese Armed Forces (LAF)—has played a pivotal role in the country’s politics. The political role of the LAF in Lebanon might seem surprising since the Lebanese state did not militarize, and its political leaders have continuously managed to keep their military relatively weak and small. Indeed, in this respect Lebanon has been markedly different from its close neighbors (Syria and Israel), but also from several other Middle Eastern states (especially Egypt and Iraq), where the military, which was large and powerful, was continuously involved in politics. Additionally, both Lebanon and the LAF have persistently striven to distance themselves from regional conflicts since 1949, particularly in relation to the Palestinian issue, albeit not always successfully. Still, and despite these ostensibly unfavorable factors for the military’s involvement in politics in Lebanon, the LAF has played an important political role in the state since its independence. This role, which has been marked by elements of continuity and change over the years, included mediation and arbitration between rival political factions (in 1945–1958, 2008, 2011, and 2019); attempts to dominate the political system (in 1958–1970 and 1988–1990); intervention in the Lebanese civil war (in 1975–1976 and 1982–1984); attempts to regain its balancing role in politics (in 1979–1982 and 1984–1988); and facilitating the state’s postwar reconstruction (since 1991). The political role of the military in Lebanon can be explained by several factors. First, the weakness of Lebanon’s political system and its inability to resolve crises between its members. Second, Lebanon’s divided society and its members’ general distrust towards its civilian politicians. Third, the basic characteristics of Lebanon’s military, which, in most periods, enjoyed broad public support that cuts across the lines of community, region, and family, and found appeal among domestic and external audiences, which, in their turn, acquiesced to its political role in the state.
