Michael II: Byzantine Emperor and Founder of the Amorian Dynasty

On this page7 sections

Introduction

Michael II, commonly known in Byzantine sources as Michael the Amorian and sometimes nicknamed the Stammerer, ruled as Eastern Roman emperor from 25 December 820 until his death on 2 October 829. He came to the throne at a moment of internal fracture and external pressure, when the imperial government had recently seen a rapid succession of commanders and the army remained the decisive force in politics. A provincial soldier by origin who rose through the ranks, Michael inaugurated the Amorian dynasty and presided over a reign that combined ruthless palace politics, a brutal civil war, and pragmatic attempts to stabilise an exhausted state. His choices on religion and on how to repair the empire’s armed forces shaped Byzantine affairs for decades.

Early Life and Rise to Power

Michael was born around 770 in Amorium, a Phrygian city that provided many of the empire’s midlevel military families. His background was modest; his family held land granted for military service and belonged to the social milieu that supplied the empire’s provincial soldiers. He entered imperial service as a cavalry officer and became attached to Bardanes Tourkos, a senior general, by marriage into Bardanes’ household. That connection placed Michael alongside other ambitious commanders, most notably Leo the Armenian, with whom he later formed a close, then fractured, partnership.

When Bardanes’ revolt collapsed in the early 800s, Michael and Leo defected and benefited from imperial clemency. In the following years Michael advanced to prominent commands and by 813 he was a trusted member of the military elite under Leo V. He played a role in Leo’s removal of Michael I Rhangabe and gained command of the Excubitors, the imperial guard unit, a post that brought both power and proximity to the palace. Relations with Leo soured after a personal dispute that culminated in Michael being implicated in a conspiracy against the emperor. Imprisoned and condemned, Michael seized a last opportunity: his supporters assassinated Leo on Christmas of 820 and proclaimed Michael emperor the same day.

Consolidation of Power

Michael’s accession was not peaceful and his first years were consumed by a major insurgency led by Thomas the Slav. Thomas rallied much of Anatolia and parts of the navy, presenting himself as an alternative ruler and even arranging a coronation on the empire’s eastern frontier. The rebellion besieged Constantinople and posed an existential threat. Michael survived largely because the capital’s fortifications held and because he secured naval victories and foreign intervention that shifted the balance. In 823 a Bulgar army moved against Thomas, while a Byzantine siege compelled the rebel to capitulate. Thomas was executed and the last pockets of resistance were suppressed in the following year. The defeat of this revolt established Michael’s authority, but the civil war had inflicted deep damage on the provinces and the economy.

To consolidate his dynasty and to gain wider loyalty, Michael made two important moves. He raised his son Theophilos as co-emperor to secure succession and in marriage allied himself with the Isaurian dynasty by wedding Euphrosyne, a daughter of Constantine VI who had been in monastic life. That marriage offended some religious circles, but it lent Michael a form of dynastic legitimacy among factions that respected the memory of the previous ruling house.

Reforms and Achievements

Michael governed in a spirit of pragmatic moderation rather than ideological zealotry. On the church question that divided Byzantium, he reinstated official support for iconoclasm, yet he avoided the mass persecutions that had marked earlier episodes. Exiled bishops and prominent figures who had fled under Leo V were allowed to return to Constantinople. Michael favoured a policy of containment and legal regulation of the controversy: icons remained officially disapproved, but enforcement was less savage and the emperor sought to reduce factional violence by permitting private conscience in many parts of the empire.

On the administrative and military front, Michael inherited an army weakened by prior defeats and by the strains of civil war. His government began rebuilding the military apparatus and reasserting central control over themes that had wavered during the revolt. He offered pardons and posted trusted commanders in critical commands to restore imperial authority. Diplomatically, he continued the frontier posture across the eastern border: intermittent raids and counterattacks continued, and he used negotiation where force could not deliver decisive results. Michael also engaged with Western rulers: correspondence and gifts to the Frankish court reflect an attempt to frame Byzantine positions on religious disputes and to win allies in the west.

Though not a great patron of letters or monumental architecture in the manner of later emperors, Michael did oversee the reconstitution of governmental stability after the turbulence of the preceding decades. By naming his son and securing the succession, he established a dynasty that would govern for most of the ninth century and lay administrative foundations that later rulers could build upon.

Challenges and Failures

Michael’s reign featured important strategic setbacks that had long-term consequences. The imperial navy and army were unable to prevent the conquest of Crete in 826 by a force of Andalusian exiles, who turned the island into a base for Muslim piracy in the Aegean for over a century. Around the same period Sicily fell under sustained Arab assault following a local uprising and the invitation of North African forces; these campaigns began a lengthy struggle for control of the central Mediterranean. Both losses reflected limits in Byzantine sea power and the empire’s exhaustion after civil war.

Internally, Michael’s rise involved brutal measures. The assassination of Leo V and the mutilation of Leo’s sons to prevent dynastic claims stained his reputation and gave ammunition to clerical and monastic critics. Religious policy, while moderated in enforcement, nonetheless committed the state to iconoclasm, alienating influential clergy and later shaping historical memory of his reign in hostile sources. The civil war itself, the widespread devastation of rural areas, and the temporary breakdown of imperial authority in some Dalmatian and Adriatic towns all revealed the costs of his seizure of power.

Death and Succession

Michael II died on 2 October 829, reportedly from kidney disease. His death was followed by a peaceful succession: his son Theophilos, who had already been elevated to the purple as co-emperor, assumed sole rule. The transition avoided an immediate crisis and allowed the new emperor to inherit an apparatus whose central structures had been reestablished. Theophilos continued many of his father’s policies, including support for iconoclasm, and further reforms of the army and administration would follow under later rulers.

Legacy

Michael’s long-term significance lies less in sweeping reforms than in stabilising the imperial house after a period of violent turnover and in providing a dynastic bridge to later ninth and tenth century recoveries. The Amorian line that he founded, and the political routines he reasserted, helped set the conditions for the revival that historians associate with the middle Byzantine period. The loss of Crete and the opening of a protracted struggle over Sicily stand among the most consequential negative outcomes of his reign, for they reshaped Mediterranean naval and commercial patterns for decades.

Historians have given Michael a mixed verdict. Contemporary churchmen and later iconodule writers often portrayed him unfavourably, emphasising his provincial manners, his speech impediment, and the moral stain of palace violence. Modern scholarship recognises these criticisms while also noting his practical achievements: he survived a catastrophic civil war, restored basic government functions, and established a dynastic continuity that allowed his successors to undertake military and cultural recovery. His religious policy, officially iconoclast but administratively moderate, illustrates a ruler attempting to balance ideological commitments with the necessity of peace.

In sum, Michael II emerges as a figure shaped by soldierly origins and compelled into hard choices by the violence of Byzantine politics. His reign ended many immediate threats to imperial survival, yet it also presided over strategic losses whose effects lasted well beyond his lifetime. His most durable contribution may be dynastic: the Amorian succession and the administrative steadiness he recovered permitted the empire to renew itself in the generations that followed.
