The surviving Ethiopian chronicle record names individual episodes across two centuries of intermittent campaigns, the execution of the rebel leader Goshen and reports of mass suicide rather than conversion, but no ancient or modern historian consulted has attempted a running total across the whole span from Yeshaq to Susenyos.
What would resolve this A systematic collation of the surviving Ethiopian royal chronicles across each named campaign, of the kind that could establish a documented floor for at least the better-recorded episodes even without a claim to completeness for the whole two centuries.
