Somalia as a case study

The Somali Democratic Republic (often called Somalia) is modest in size. It is named after its people, the Somali - a largely pastoral people who are Muslims and speak the Somali language. Somalia is Africa's leading country in cultural and linguistic homogeneity of its people.
 
The country's population is slightly over 8.5 million, and is composed of various clans within the same Somali ethnic group. While most African countries are bogged down in tribalism, Somalia's stigma is that of clanism. The country's post-independence history has been largely plagued by inter-clan rivalry for power.
 
The economy of Somalia is overwhelmingly pastoral, and the majority of its people derive their livelihood from cattle, goats, sheep and camels. Livestock and their products account for over 70 percent of the country's exports. Plantation agriculture (mainly of bananas and sugar-cane) is practised in some areas in the south.
