Southern Sudan, one of the world's most underdeveloped areas, will hold a referendum in 2011 to decide if it will break away from Sudan to form a new nation. This is significant because this is the culmination of long-time tensions between the North and South, with (at the risk of simplifying the state of affairs) the former's people being mostly Arabic-speaking and Muslim, and the latter being mostly non-Muslim. The area has experienced heavy violence and severe humanitarian troubles, raising fears from some who feel this is part of a plot to undermine the fragile peace in the region and intensify conflicts amongst the people in the South with each other.

The South fought a bitter and devastating war with the Sudanese government that lasted over 20 years (from the early eighties to 2005) and killed over a million people. The two sides signed an agreement that has continued till the present, but with one of the conditions being a referendum for secession. It will be tough if the referendum actually succeeds, given the humanitarian problems and violence, so any fledgling South Sudan state will have its work cut out.
