Many of the farmers in the villages of the South and East are descendants of nomadic herders who have settled in the past 100 years. Groups of these people formed tribal units. Social and political relations were largely feudal and the measure of strength was the number of warriors at the command of each group. Weak tribes depended on the strong and gave them economic and military support in exchange for protection.

Because of the changes through government settlement programs and modernized farming, families are being detached from traditional structures in order to compete with others for jobs. Therefore these kinds of villages are losing their typical characteristics.
