In 2011, residents of Blue Nile were scheduled to hold ill-defined "popular consultations" to determine the constitutional future of the state, per the
Comprehensive Peace Agreement. Instead, a dispute over the rightful government of the state, and the determination of
Omar al-Bashir to eradicate the
Sudan People's Liberation Movement–North, led to
a renewed nine-year conflict between government forces and the
Sudan Revolutionary Front as well as contributing to a refugee crisis. The conflict finally came to an end in 2020 after a peace agreement was signed and the government to not discriminate based on ethnicity or religion.
Further clashes in the state broke out in 2022 between the
Hausa people and
Funj and
Berta peoples over land disputes which led to the deaths of hundreds of civilians. On 5 August 2024, the RSF launched an incursion into the state and continues to control northwestern parts of the state. On 5 March 2025, SAF launched a counteroffensive on the rest of RSF controlled territory in
Sennar, and took full control over territories, including
Mazmoum. In 2026,
conflict renewed as the RSF and SPLM-N launched an offensive from the Ethiopian border, capturing Kurmuk and the southern areas of the state. == Administration ==
