Sudan ( soo-DAN; officially the Republic of the Sudan) (Arabic: السودان As Sūdān) is a country in northeastern Africa. It is bordered by Egypt to the north, the Red Sea to the northeast, Eritrea and Ethiopia to the east, South Sudan to the south, the Central African Republic to the southwest, Chad to the west, and Libya to the northwest. The world's longest river, the Nile, divides the country between east and west sides.
Sudan is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 3000 BC. The people of Sudan have a long history extending from antiquity, which is intertwined with the history of Egypt, with which it was united politically over several periods. After gaining independence from Egypt, and the United Kingdom in 1956, Sudan suffered a civil war, lasting 17 years, subsequently followed by ethnic, religious, and economic conflicts between the Northern Sudanese (with Arab and Nubian roots), and the Christian and animist Nilotes of Southern Sudan. Thus this led to a second civil war in 1983, and due to continuing political and military struggles, Sudan was seized in a bloodless coup d'état by colonel Omar al-Bashir in 1989, who thereafter proclaimed himself President of Sudan.
Sudan then achieved great economic growth
by implementing macroeconomic
reforms and finally ended the civil war by adopting a new constitution
in 2005 with rebel groups in the south, granting them limited autonomy to be followed by a referendum about independence
