Uganda, officially the Republic of Uganda (Swahili: Jamhuri ya Uganda), is a country in East-Central Africa. It is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania. The southern part of the country includes a substantial portion of Lake Victoria, shared with Kenya and Tanzania. Uganda is in the African Great Lakes region. Uganda also lies within the Nile basin, and has a varied but generally a modified equatorial climate. Uganda takes its name from the Buganda kingdom, which encompasses a large portion of the south of the country, including the capital Kampala. The people of Uganda were hunter-gatherers until 1,700 to 2,300 years ago, when Bantu-speaking populations migrated to the southern parts of the country. Beginning in 1894, the area was ruled as a protectorate by the UK, who established administrative law across the territory. Uganda gained independence from the UK on 9 October 1962. The period since then has been marked by intermittent conflicts, including a lengthy civil war against the Lord's Resistance Army in the Northern Region led by Joseph Kony, which has caused hundreds of thousands of casualties. The official languages are English and Swahili, although "any other language may be used as a medium of instruction in schools or other educational institutions or for legislative, administrative or judicial purposes as may be prescribed by law." Luganda, a central language, is widely spoken across the country, and several other languages are also spoken including Runyoro, Runyankole, Rukiga, Luo, and Lusoga.
