Constantine V had chosen his son’s wife by holding an empire-wide beauty contest and had settled on Irene, a devastatingly attractive orphan from Athens. For the arch iconoclast, it was a remarkably bad choice. Having grown up in the West, Irene was a fervent supporter of icons who had no use for her father-in-law and secretly made it her life’s goal to restore icons to veneration. Her husband tried to rein her in, but a month after consigning her to a wing of the palace, he was dead, and Irene was spreading the suspicious rumor that his death was the result of divine retribution. Whether the citizens of Constantinople believed her or not, they grudgingly accepted Irene as regent for her ten-year-old son, Constantine VI, and in doing so gave the throne to one of the most grasping rulers in Byzantium’s long history. For those who stood in her way, the young empress had no mercy, and she was determined to cling to power no matter what the cost.
For the next eleven years, the empress ruled with an iron hand, carefully removing iconoclasts from important posts and replacing them with her supporters. Unfortunately for the empire, most of its best officers and soldiers were iconoclasts, and their removal crippled the imperial army. Faced with a massive Muslim invasion two years into her regency, the demoralized and weakened Byzantine army simply defected and joined the Arabs. The humiliating and expensive peace Irene was forced to buy severely damaged her popularity, and insistent voices began calling for her to relinquish the regency.
Military reversals and declining public support, however, meant little to Irene. She was focused on restoring icons to veneration and continued smoothly with her religious program. However powerful the iconoclast emperors had been, they had lacked the full authority of the church, and Constantine V’s hollow attempt at an ecumenical council had fooled no one. Irene would put the question of iconoclasm to the whole body of the church, sure that the weight of their one voice would bury the iconoclasts forever. Ambassadors were sent scurrying to the patriarchs of Alexandria, Antioch, Jerusalem, and Rome, inviting them to what would be the eighth and final great ecumenical council of the church.
It convened in the capacious Church of the Holy Wisdom in Nicaea, the scene of the first council 462 years before, and its findings were hardly surprising. Iconoclasm was condemned, but the faithful were admonished to take care that veneration didn’t stray into worship. The empire greeted the news with relief, believing that perhaps the long nightmare was over. Iconoclasm had been waning for decades, and had been driven largely by zealous emperors. When it was condemned, not a single voice was raised to defend it.
The religious victory should have provided a high note for Irene to end the regency and turn over effective power to her son. Traditionally, regencies ended when their charges were sixteen, and Constantine VI was now in his twenties. Irene, however, had always been more interested in power than anything else, and she was not about to relinquish it in favor of her pathetic son. Constantine VI was a weak-enough man to be easily manipulated, and all would have been well if Irene could have controlled her ambition, but such restraint wasn’t in her nature. Banishing her son’s face from the imperial currency, she issued coins that featured only images of herself on both sides.*
Not content with this unnecessary insult, she then produced an imperial decree announcing that she was the senior emperor and as such would always take precedence over Constan tine VI. When several generals protested, demanding that the rightful emperor be given the throne, Irene angrily executed them and had her bewildered son savagely beaten and thrown into a dungeon.The empress could hardly have handled the situation more poorly. Even a successful emperor would have thought twice before antagonizing the army, and militarily Irene had been nothing short of a disaster. Thanks to her endless purges, the army had been performing poorly throughout her reign, and its loyalty to her was correspondingly weak. The last two years had seen major imperial defeats against the Arabs, the Bulgars, and the Franks, and there was a lingering suspicion that perhaps the iconoclasts had been right after all. Revolt swept through the ranks of the army. Soon angry mobs were swarming the streets of Constantinople, calling for Irene to step down in favor of her son. Transformed overnight from a prisoner to a folk hero, Constantine VI was swept from his jail cell to the throne, and Irene was placed under house arrest in one of her many palaces.
