To the Italian historian the Battle of Adwa in March 1896 has offered a field of interpretation which has been heavily marked by the events that occurred between (and within) the two countries—Ethiopia and Italy—before and after the battle. Adwa has been variously depicted by Italian historiography of the liberal period as a major military defeat, a political mistake by Crispi's expansionist government and the result of deep contrasts within the newly born state over the ‘colonial burden'. Fascist historiography painted Adwa as proof of liberal decay and political inefficiency. Adwa's name could be avenged only in the battlefield, which was done during Mussolini's invasion of Ethiopia in 1935-36. From the Ethiopian point of view, Adwa's image changes no less. Until recently, the Battle of Adwa was painted as the landmark for Ethiopian unification and independence during the colonial era. Menelik's momentous victory at Adwa crowned his bid for power in the national arena, while his successful ability to stave off external colonial pressure appeared to cancel, or rather conceal, the internal policy of expansion and consolidation of his country's rule in the region. Today's insistence on Adwa as an African victory appears to be the dominant historiographical representation. The different interpretations all contain elements of truth, yet all, if frozen into historiographical truths, become embarrassing to the historian who needs documents, rather than monuments, as tools of analysis. To many historians both in Italy and Ethiopia, Adwa's respective symbolism of victory/defeat has been transformed into an icon, an historiographical monument, unassailable and immovable. The centenary of Adwa allows us to reconsider historical events of a shared past as critical documents and biased representations reflecting their own culture and time. This article attempts to deconstruct the historiographical monument of Adwa in Italian society so as to transmit such a heavily coded event to the critical examination of future historians in both Italy and Ethiopia.
