XX. Manzikert. (1057-1081.)
The moment that the last of the Macedonian dynasty was gone, the elements of discord seemed unchained, and the double scourge of civil war and foreign invasion began to afflict the empire. In the twenty-four years between 1057 and 1081 were pressed more disasters than had been seen in any other period of East-Roman history, save perhaps the reign of Heraclius. For now came the second cutting-short of the empire, the blow that was destined to shear away half its strength, and leave it maimed beyond any possibility of ultimate recovery.
Domestic troubles were the first inevitable consequence of the extinction of the Macedonian dynasty. The aged Theodora had named as her successor on the throne Michael Stratioticus, a contemporary of her own who had been an able soldier twenty-five years back. But Michael VI. was grown aged and incompetent, and the empire was full of ambitious generals, who would not tolerate a dotard on the [pg 250] throne. Before a year had passed a band of great Asiatic nobles entered into a conspiracy to overturn Michael, and replace him by Isaac Comnenus, the chief of one of the ancient Cappadocian houses, and the most popular general of the East.
Isaac Comnenus and his friends took arms, and dispossessed the aged Michael of his throne with little difficulty. But a curse seemed to rest upon the usurpation; Isaac was stricken down by disease when he had been little more than a year on the throne, and retired to a monastery to die. His crown was transferred to Constantine Ducas, another Cappadocian noble, who was supposed to be second only to Isaac in competence and popularity. Constantine reigned for seven troubled years, and disappointed all his supporters, for he proved but a sorry administrator. His mind was set on nothing but finance, and in the endeavour to build up again the imperial treasure, which had been sorely wasted since the death of Basil II., he neglected all the other departments of state. To save money he disbanded no inconsiderable portion of the army, and cut down the pay of the rest. This was sheer madness, when there was impending over the empire the most terrible military danger that had been seen for four centuries. The safety of the realm was entirely in the hands of its well-paid and well-disciplined national army, and anything that impaired the efficiency of the army was fraught with the deadliest peril.
The Seljouk Turks were now drawing near. Pressing on from the Oxus lands, their hordes had overrun Persia and extinguished the dynasty of the Buhawides. [pg 251] In 1050, they had penetrated to Bagdad, and their great chief, Togrul Beg, had declared himself “defender of the faith and protector of the Caliph.” Armenia had next been overrun, and those portions of it which had not been annexed to the empire, and still obeyed independent princes, had been conquered by 1064. In that year fell Ani, the ancient Armenian capital, and the bulwark which protected the Byzantine Empire from Eastern invasions.
The reign of Constantine Ducas was troubled by countless Seljouk invasions of the Armeniac, Anatolic, and Cappadocian themes. Sometimes the invaders were driven back, sometimes they eluded the imperial troops and escaped with their booty. But whether successful or unsuccessful, they displayed a reckless cruelty, far surpassing anything that the Saracens had ever shown. Wherever they passed they not merely plundered to right and left, but slew off the whole population. Meanwhile, Constantine X., with his reduced army, proved incompetent to hold them back; all the more so that his operations were distracted by an invasion of the Uzes, a Tartar tribe from the Euxine shore, who had burst into Bulgaria.
Ducas died in 1067, leaving the throne to his son, Michael, a boy of fourteen years. The usual result followed. To secure her son's life and throne, the Empress-dowager Eudocia took a new husband, and made him guardian of the young Michael. The new Emperor-regent was Romanus Diogenes, an Asiatic noble, whose brilliant courage displayed in the Seljouk wars had dazzled the world, and caused it to forget that caution and ability are far more regal virtues than [pg 252] headlong valour. Romanus took in hand with the greatest vigour the task of repelling the Turks, which his predecessor had so grievously neglected. He led into the field every man that could be collected from the European or Asiatic themes, and for three successive years was incessantly marching and counter-marching in Armenia, Cappadocia, and Syria, in the endeavour to hunt down the marauding bands of the Seljouks.
The operations of Romanus were not entirely unsuccessful. Alp Arslan, the Sultan of the Seljouks, contented himself at first with dispersing his hordes in scattered bands, and attacking many points of the frontier at once. Hence the Emperor was not unfrequently able to catch and slay off one of the minor divisions of the Turkish army. But some of them always contrived to elude him; his heavy cavalry could not come up with the light Seljouk horse bowmen, who generally escaped and rode back home by a long detour, burning and murdering as they went. Cappadocia was already desolated from end to end, and the Turkish raids had reached as far as Amorium, in Phrygia.
