Abstract

This paper tries to answer the object of the custum presence in traditional Algerian society in light of the cultural system approaches; we treat it both in theory and practice within the contemporary Algerian novel. Analysing the novel « Lailat Houroub Fadjra », we picked up that the custum has an absolute power in the Algerian traditional society, that may qualify it to become a cultural and rhetorical type that contributes in standardizing this society. We noticed how the custum in Sahara society became a strict social rule in the questions of marriage, women's rights, freedom, the tyranny, and also in the concept of love, religion rites and all thier uses in protecting of this society.
