Each axis runs from −10 to +10, with zero a genuine mixed or balanced position rather than an absence of opinion. A score describes a stated position and a governing record; it is not a judgement of merit. What each score means →

Core principles

An attempt at independence by the Igbo-majority east after pogroms in the north, defeated by blockade and starvation.

Economic model

Oil in the secessionist territory was the war's central material stake.

Organisation of powers

A military governorship with wartime emergency powers.

Reading note

Between half a million and two million civilians died, most of hunger. The war fixed the principle that African colonial borders would not be redrawn.
