Burundi (pronounced /bəˈɹʊndɨ/), officially the Republic of Burundi (Kirundi: Republika y'u Burundi, [buˈɾundi]; French: République du Burundi, [byˈʁyndi]), is a 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 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, in part, 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.
