The National Democratic Alliance (NDA) is a group of Sudanese political parties that was formed in 1989 to oppose the regime of Omar Hassan al-Bashir after he seized power in a military coup on June 6, 1989. The NDA signed a deal with the Sudanese government on June 18, 2005, following a peace agreement to end the Second Sudanese Civil War on January 9, 2005. Some issues have yet to be resolved by opposing factions, including the conflict and humanitarian issues in the war-torn region of Darfur. After further violent clashes in the east, a separate peace deal was signed with the Beja Congress in October 2006.
