Tribal System and Governmental pattern in Iran

The climate, the natural environments of Iran and tribal and nomadic system provided the grounds for the tribes to dominate the political and governmental system of this country in the course of history. The spontaneous invasion of the tribes and nomads and the flow of the population to the sedentary societies institutionalized their effects on the political and governmental pattern of Iran. Thus, this paper attempts to study the structure of tribal community and its effects on the political and governmental system of this country.
