The recurring Enugu patterns: (1) industrial-labour state violence (Iva Valley 1949 → colliery strikes → 2009 land riots); (2) ethnoreligious frontier violence in the Uzo-Uwani / Isi-Uzo border belt; (3) Biafra-legacy security operations (1967–70 → Python Dance → IPOB sit-at-home); (4) coal-dispossession grievance (Ngwo land never restituted).
