Somalia
There are four big tribes in Somalia, the Hawiye, the Dirweyn, the Koofur Orsi inhabitants and the Darood. Somalis are a nation of related families, which are called clans. Groups of clans sometimes band together based on a common ancestor or other blood relationship. Sometimes these family relationships date back hundreds or even thousands of years in the past. Somalis are mostly camel or goat herders, and depend on their livestock to live. In Somalia there are limited sources of drinking water and grazing land, and disputes over grazing rights, water rights, or land in general can lead to fighting between families. Because of the clan system, the families involved will call on their clan for help, leading to a clan war. The discovery of oil and minerals in Somalia, as well as the power and money associated with politics and business, has created more opportunities for families to get ahead, and has also created more reasons for families to have disputes.
