Crises & Protests — Ebonyi State

Ebonyi's crisis history is dominated by three axes: the Aro slave corridor and the 1901–02 British conquest; chronic intra-Igbo land wars between Ezza, Ezillo, Effium, Ikwo and Agila (Benue) clans; and the lead-poisoning crisis in the Enyigba-Ameka mining belt. Each bullet auto-classifies into one of the seven recurring Patterns of Violence.

Pre-colonial — Aro slaving and salt wars (pre-1900)#Deep dive →

Aro-Ibiniukpabi slave traffic (c. 1650–1902) — the Long Juju oracle at Arochukwu drew "convicted" parties through the Ebonyi salt corridor for sale at Calabar and Bonny; estimated tens of thousands of Cross River Igbo embarked across the period.
Ezza expansion wars (17th–19th c.) — Ezza-Ezekuna *ogwa* warriors push west into Ezillo, Effium and Ezzangbo; the foundational land-claim disputes that recur into the 21st century.
Salt-spring control fights at Uburu, Okposi and Enyigba — periodic raids documented in oral histories.
