Coupling Geometry Case Study XI: The Ethiopian Empire, 1270–1974

This case study applies Coupling Geometry to the Ethiopian Empire under the Solomonic dynasty, 1270–1974, and is the document in which the programme first recorded a failure. The case was selected adversarially and for that stated reason: after twelve systems and an unbroken record of confirmations, the author’s own assessment was that a perfect record across that many cases is methodologically suspicious, and Ethiopia was chosen as the case most likely to produce a failure. It did. Ten derivations were made. Nine are consistent with the record — a territorial highland base producing land-tenure obligations tied to military service; provincial lords holding real regional autonomy; the redistribution theorem holding through to the 1974 revolution; Ethiopian Orthodoxy as one of the strongest non-materially contingent ideologies in the portfolio; an identity function constitutive enough to sustain resistance through the sixteenth-century invasion and the Italian occupation; feudal provincial decoupling that carried the system through the near-century of the Zemene Mesafint; and an oscillating rather than linear expansion lifecycle. The tenth failed. Under the narrow definition of a structural buffer — a geographic feature that physically prevents military access, demonstrated by at least one invasion physically stopped — the Ethiopian highlands do not qualify. Armies crossed them repeatedly across seven centuries. Ethiopia therefore achieved seven hundred years of longevity without the geographic condition the programme had held to be necessary, and the condition’s claim to universality is falsified. The paper records what followed: the condition was reformulated, tested again on the Khmer Empire, falsified again, and reformulated a second time. It also records that the programme’s own deposited empirical companion identifies this sequence as the pattern Lakatos calls potentially degenerative and names the condition the framework’s most exposed locus. Adversarial examination by Ethiopianists is invited. Case Study X: The Ottoman Empire, 1299–1922 – Case Study XII: The Khmer Empire, 802–1431
