The importance of the countryside (rief) for the social and economic development of Arab societies whose populations are still greatly peasant in composition and whose wealth is still based on agriculture seems incontestable. Less obvious, but equally important, is the political role of the peasantry and the rural areas in the process of transition from traditional to more modern types of social and political systems in the Middle East. There is plenty of evidence that political modernization cannot take place without a solution to the peasant problem — without their incorporation into the political system. Huntington holds that in modernizing countries where the bulk of the population is rural but where politics remains a predominately urban game, governments are likely to be ephemeral, unstable and ineffective. He argues that the establishment of stable and effective regimes requires bridging the urban-rural gap through some coalition of urban and rural forces which will bring the peasantry into the system. Furthermore, both Huntington and Barrington Moore argue that the particular type of leadership under which the peasants are brought into the political system greatly shapes the whole subsequent development of the system. The countryside, according to Huntington, plays a crucial swing role and this role varies from very conservative to very revolutionary. Three possibilities seem to be typical. One outcome is where peasants are brought into the system by upper-class leadership, sometimes through a formally liberal type electoral system, informally based on patronage and traditional symbolism, sometimes through a conservative authoritarian system.
