This chapter provides a micro-level analysis of why and how the reformist insurgency-society contract formed between the Union for Democratic Forces for Unity (UFDR) and the northeastern societal group in the Central African Republic (CAR) (2006–2008) through the Grievance-Driven Pathway using the Comprehensive Social Contract (CSC) Framework. With the northeast’s marginalization from CAR’s state-society contract, many began to self-identify as “northeasterners”—cross-cutting ethnic identity, ancestry, language, and religion—through predominantly an in-group process. The government’s failure to build a memorial monument mobilized the northeast’s general population toward unorganized opposition and mobilized the insurgency’s first actors toward armed opposition, notably Zacharia Damane. The government’s predation in the region and Damane’s arrest led to the spontaneous establishment of the UFDR and its bonding with the northeastern society. The UFDR drew on the region’s pre-war social bases and was perceived as legitimate due to its shared values and mandate for self-defense, to agitate to get the government’s attention, and to reform the state-society contract. Despite the government’s effective counterinsurgency campaign against the UFDR, the unmitigated and compounding grievances have sustained, in part, an insurgency in the region—led by many of the former UFDR’s leaders but under the banner of numerous different armed groups.
