3oo LAW AND FREEDOM IN HISTORY nomic centre of gravity. These facts were the politically pertinent facts when, in the fifth century, Italy slipped out of the Imperial Government's control; yet present political realities counted for less in determining the emotional reaction of Constantinople to the eclipse of the Imperial Government's authority in Italy in this age than the historic role once played by a Roman Italy in the creation of a Roman Empire in a past age which had long since become ancient history. The de facto sovereignty of barbarian war-lords in Italy was never recognized at Constantinople de jure i and the work of financial, economic, and military reconstruction, that a Constantinopolitan Imperial Government had gradually carried out during the fifth century in the Central and Oriental provinces,1 had no sooner borne fruit in the accumulation of a reserve of public resources than this reserve was squandered by the sixth-century Constantinopolitan Emperor Justinian on the archaistic enterprise of re-subjugating Italy to the direct rule of a Roman Imperial Govern- ment. This political objective was duly attained by Justinian at the cost of an eighteen-years-long war (gerebatur A.D. 535-53). But, within five years of the collapse of the last Gothic resistance to Roman arms on Italian soil in A.D. 563,2 the laboriously reconquered Italian dominions of the Roman Imperial Crown were lost again to yet another war-band of barbarian invaders. The Lombard irruption into Italy, which broke upon her in A.D. 568, did not come to a standstill until it had robbed the Empire of the whole of Italy save for seven bridgeheads on the beaches3 and a line of isolated inland fortresses,4 strung along the road between Ravenna and Rome, which survived, like stepping-stones, amid an encompassing flood of Lombard invasion that had swirled round their walls on its torrential course from the Po Basin into the Abruzzi. This prompt re- sumption of the march of History in reply to Justinian's archaistically conceived counter-attack was even less surprising than the anticipation of a post-Justinianean Alboin's exploit by his pre-Justinianean forerun- ners Ricimer, Odovacer, and Theodoric; for Justinian's ephemeral con- quest of Italy for a Constantinopolitan Roman Empire had been pur- chased at the threefold price of ruining the Empire's revenue-producing Oriental provinces, depopulating her military recruiting grounds in the Danubian provinces, and alienating the 'liberated' Italians by first devastating Italy in the act of exterminating the Ostrogoths and then wringing revenue out of her for the treasury of a Transadriatic Imperial Government to whose jurisdiction Italy had never been subject before her annexation to it by Justinian himself. In these circumstances it would have been a miracle if Justinian's conquest of Italy had had any enduring effect.
