Abstract EN:

The study deals with the failure of the Lebanese State system, its impossibility to tackle the crisis and the demographic consequences of the conflict in Lebanon from the early stages of the Lebanese conflict in 1975 up to 2009. The interest of the subject consisted in dealing with the consequences of the different Lebanese wars (from 1975 to 1990) between the different communities and this through the concept of State and the way it was understood within the different communities. Our study is part of a sociological, demographic, political and historic study. The chronology has not been systematically respected. We went to back and forth on the political history of Lebanon trying to better understand the reasons of these different conflicts. After a necessary introduction to situate the question in its context recalling thus the main outlines of the Lebanese contemporary history, the State as a legal entity, the utmost step of accomplished societies, will be studied. The study will then focus on its incapacity to face the crisis to finally concentrate on the internal and external migrations of the different communities and the demographic consequences of the conflict. We will also consider Lebanon in its geographical frame and political environment as this country can only be understood through the Israeli-Arab conflict that remains in a certain way the background of the issue. We will then study the 1990-2009 period that can be called "the years of reconstruction" and about which a lot has been discussed in goods or bad terms. A linguistic section will also be considered so as to provide the author's vision on the way to express political concepts in classical Arabic as well as on peculiar expressions in dialectal Arabic. Additionally, the 33-day war from 2006 will compose a part that appeared as being necessary.
