The Sudanese conflict in South Kordofan and Blue Nile in the early 2010s between the Army of Sudan and the Sudan Revolutionary Front started as a dispute over the oil-rich region of Abyei in the months leading up to South Sudanese independence in 2011, though it is also related to civil war in Darfur that is nominally resolved. The events would later be known as the Sudanese Intifada, which would end only in 2013 after al-Bashir promised he would not seek re-election in 2015. He later broke his promise and sought re-election in 2015, winning through a boycott from the opposition who believed that the elections would not be free and fair. Voter turnout was at a low 46%.
