Burundi is a small country in East Africa bordered by Tanzania, Rwanda, and Lake Tanganyika. Burundi gained its independence from Belgium in 1962. Much of its history has been turbulent, and Burundi's first democratically elected president was assassinated in October 1993 after only 100 days in office. The internationally brokered Arusha Agreement ended the 1993-2005 civil war, paving the way for a new constitution and 2005 elections. Pierre NKURUNZIZA was elected president in 2005 and 2010 and again in a controversial election in 2015. Burundi continues to face many political and economic challenges.
