By the end of the sixth century, the reconquests that had cost so much blood and treasure to gain had been carelessly thrown away, and the empire was retreating on all fronts.*
In Constantinople, a demented usurper without a shred of legitimacy named Phocas seized the throne, and the Balkans disappeared under a flood of Slavic invasion. Armies pushed beyond endurance were demoralized and disorganized, unwilling to fight for an uninspiring and corrupt government. Any wealth that escaped the clutches of the imperial tax collectors disappeared into the bottomless pockets of barbarian hordes that seemed to appear with depressing regularity. Refugees packed the cities, trade slowed to a crawl, and weeds and ruins choked the once-fertile fields. The empire was a spent force, a broken reed, the luster of its past a fading memory.Virtually the only area of the empire that wasn’t collapsing was the prosperous coast of North Africa. There, under the warm sun, merchants continued to ply the waters of its harbors unmolested, and farmers harvested its fertile wheat fields. The province seemed far away from the swirling revolts and chronic unrest that had so thoroughly destroyed imperial prosperity, and some in Constantinople began to see it as the only chance of salvation. Disgusted by their bloody emperor, the Senate wrote secretly to the governor of North Africa, urging him to come at the head of an army and deliver the empire from its present nightmare.
When the letter arrived in Carthage, the governor read it with considerable interest. He was far too comfortable where he was, and, in any case, he felt himself to be too old to go gallivanting around, so he sent his son Heraclius with the African fleet to seize the throne in his stead.
The young man knew he had to act quickly. Each passing day seemed to bring the empire closer to destruction: While the government in Constantinople concentrated on purging itself of suspected dissidents in a horrifying bloodbath, the Persian king Chosroes II took advantage of the distraction to invade. Meeting only token resistance from the demoralized imperial army, the Persians quickly overran Mesopotamia and Armenia, plunging deeply into the Byzantine heartland and even probing into Egypt. Before long, Persian watch fires could be seen from the walls of Constantinople; and as panic rippled through the capital, the plague returned, bringing with it terrified prophecies of the end of the world.
It was at this moment, with the population of the capital at a fever pitch, that Heraclius arrived in the imperial harbor on board his magnificent flagship. At the sight of the vessel, a mob in Constan tinople lynched his predecessor, Phocas, dragging the mutilated corpse through the streets. Picking his way through the despoiled palace with care, Heraclius took stock of his shattered empire. It had lost nearly half of its territory, and what was left was demoralized and impoverished, but its roots were deep, and Heraclius was already starting to plan. The empire of the past was gone—of that he was confident. His task was to create something new—an empire that embraced its future. Byzantium would never be the same again.
The crowd milling about outside the imperial palace in the bright October sun of AD 610, waiting to catch a glimpse of their new emperor, didn’t quite know what to expect. He’d appeared seemingly out of nowhere like the Athena of their old pagan myths, springing fully grown out of the head of Zeus. There was an aura of success about him, and he was undeniably physically impressive. Barely thirty-six, with a full head of golden hair and impossibly burnished armor, he looked every inch an emperor, like some new Achilles appearing at Byzantium’s darkest hour. Energetic and hardworking, the emperor had the rare ability to inspire confidence in even the most desperate circumstances, and he threw himself into the task of rescuing the empire.
The challenges confronting him were enormous. The once-vaunted imperial army was scattered helplessly before its enemies, and Greece was buried beneath a Slavic flood. Refugees crowded into Constantinople, soon bringing with them news too terrible to comprehend. At first, it was only whispered in disbelief, but it spread like wildfire. Jerusalem had fallen to the Persians, and the True Cross was now in the hands of the fire worshippers of Ctesiphon.*
All male citizens of Jerusalem had been killed, and the women and children had been sold into slavery.
