Burundi, officially the Republic of Burundi, is a small landlocked country in the Great Lakes region of Eastern Africa bordered by Rwanda to the north, Tanzania to the east and south, and the Democratic Republic of the Congo to the west. Its size is just under 28,000 km² with an estimated population of almost 8,700,000. Its capital is Bujumbura. Although the country is landlocked, much of the southwestern border is adjacent to Lake Tanganyika.
The Twa, Tutsi, and Hutu peoples have occupied Burundi since the country's formation five centuries ago. Burundi was ruled as a kingdom by the Tutsi for over two hundred years. However, at the beginning of the twentieth century, Germany and Belgium occupied the region, and Burundi and Rwanda became a European colony known as Ruanda-Urundi.
Political unrest occurred throughout the region because of social differences between the Tutsi and Hutu, provoking civil war in Burundi throughout the middle twentieth century. Presently, Burundi is governed as a presidential representative democratic republic. Sixty-two percent of Burundians are Roman Catholic, eight to ten percent are Muslims and the rest follow indigenous beliefs and other Christian denominations.
Burundi is one of the ten poorest countries in the world. It has the lowest per capita GDP of any nation in the world. Burundi has a low gross domestic product largely due to civil wars, corruption, poor access to education, and the effects of HIV/AIDS. Burundi is densely populated, with substantial emigration. Cobalt and copper are among Burundi's natural resources. Some of Burundi's main exports include coffee and sugar.
