Malawi, officially the Republic of Malawi, is a landlocked country in southeast Africa that was formerly known as Nyasaland. It is bordered by Zambia to the northwest, Tanzania to the northeast, and Mozambique on the east, south and west. The country is separated from Tanzania and Mozambique by Lake Malawi. Malawi is over 118,000 km2 with an estimated population of 16,777,547. Its capital is Lilongwe, which is also Malawi's largest city; the second largest is Blantyre and the third is Mzuzu. The name Malawi comes from the Maravi, an old name of the Nyanja people that inhabit the area. The country is also nicknamed "The Warm Heart of Africa".The area of Africa now known as Malawi was settled by migrating Bantu groups around the 10th century. Centuries later in 1891 the area was colonized by the British. In 1953 Malawi, then known as Nyasaland, became part of the semi-independent central African Federation. The Federation was dissolved in 1963 and in 1964, Nyasaland gained full independence and was renamed Malawi. Upon gaining independence it became a single-party state under the presidency of Hastings Banda, who remained president until 1994, when he was ousted from power. Joyce Banda is the current president, raised to that position after president Bingu wa Mutharika died in 2012. She is the first female president in Malawi.. Malawi has a democratic, multi-party government. Malawi has a small military force that includes an army, a navy and an air wing. Malawi's foreign policy is pro-Western and includes positive diplomatic relations with most countries and participation in several international organisations.Malawi is among the world's least-developed countries. The economy is heavily based in agriculture, with a largely rural population. The Malawian government depends heavily on outside aid to meet development needs, although this need has decreased since 2000. The Malawian government faces challenges in building and expanding the economy, improving education, health care, environmental protection, and becoming financially independent. Malawi has several programs developed since 2005 that focus on these issues, and the country's outlook appears to be improving, with improvements in economic growth, education and healthcare seen in 2007 and 2008.Malawi has a low life expectancy and high infant mortality. There is a high prevalence of HIV/AIDS, which is a drain on the labour force and government expenditures. There is a diverse population of native peoples, Asians and Europeans, with several languages spoken and an array of religious beliefs. Although there was periodic regional conflict fueled in part by ethnic divisions in the past, by 2008 it had diminished considerably and the concept of a Malawian nationality had reemerged. Malawian cultural practices and Malawian cuisine are rich in local, southern African, and overseas influences.
