Philippicus: Byzantine Emperor and His Impact on Early 8th Century Empire

On this page7 sections

Introduction

Philippicus, who ruled the Byzantine Empire from late 711 until the summer of 713, was a short-lived emperor whose accession interrupted the decade-long dominance of the Heraclian dynasty. Born Bardanes (also rendered Vardan), he emerged from the empire’s eastern aristocracy and gained the throne by fomenting revolt in a remote provincial possession. His reign is best remembered for an abrupt religious reversal, a string of foreign incursions that tested imperial defenses, and a violent overthrow that ended in mutilation and exile. Although his time on the throne was brief, Philippicus’ decisions on theology and patronage produced ripples across church relations with Rome and among Christian communities in the Near East.

Early Life and Rise to Power

Philippicus was born Bardanes into a prominent family with connections to the empire’s Armenian-speaking provinces. His father, Nicephorus, held patrician rank and the family maintained ties with established aristocratic circles in Anatolia. Contemporary and later accounts emphasize Bardanes’ education and oratorical skill in Greek, suggesting he was literate and cultivated in the intellectual norms of Constantinople.

Under the emperors who preceded him Bardanes served at court and in military commands, but he also attracted suspicion by voicing imperial ambitions. For this reason successive rulers sent him away from the capital, first to islands in the Aegean and later to the Black Sea possession of Cherson. In the geopolitical disorder that followed the return of Justinian II to power, the exiled Bardanes won the support of Cherson’s notables and the Khazar leadership. With backing from naval officers who switched allegiances, he sailed on Constantinople and entered the capital in late 711, taking the regnal name Philippicus. His ascent was swift and brutal: Justinian II and members of his household were captured and executed, and the new regime moved quickly to eliminate prominent loyalists to the deposed emperor.

Consolidation of Power

Once in control of Constantinople, Philippicus pursued immediate measures to secure his position and to signal a new political order. He removed the sitting patriarch of Constantinople, replacing him with a cleric more aligned with his theological preferences, and convened a gathering of eastern bishops sympathetic to his views. Those moves were intended to consolidate ecclesiastical support within the Greek-speaking church hierarchy, but they also provoked rejection from the Roman pontiff and parts of the western church.

Domestically, Philippicus attempted to strengthen his legitimacy by restoring certain aristocratic networks that had been marginalized under Justinian II. He also engaged in acts of public patronage that associated his image with urban monuments and elite social spaces in the capital. These steps were designed to bind influential urban constituencies to his person, but they proved insufficient to overcome military discontent among the empire’s provincial troops.

Reforms and Achievements

Because his reign lasted less than two years, Philippicus had little opportunity to implement sweeping structural reforms. Nevertheless, he moved decisively in a few areas that illustrate his priorities. In religious policy he repudiated the theological settlement of the late seventh century by repudiating the canons of the council that had condemned monotheletic formulas, and he sought to promote a doctrine aimed at reconciling Greek and certain oriental Christian communities. To reinforce this program he appointed sympathetic bishops and authorized a compact assembly of eastern prelates to endorse his line.

On the diplomatic front Philippicus made gestures intended to preserve or restore ties with neighbouring Christian polities. He released hostages from the Caucasian principalities and presented sacred relics as gifts, efforts that sought to maintain alliances along the empire’s northeastern frontier. In Italy he took initiatives to restore ecclesiastical property and to reestablish links with the Byzantine administration of Ravenna, which had suffered under his predecessor. In the capital he cultivated a visible image through architectural commissions and representations on coinage and seals that emphasized his imperial dignity, though he abandoned some of the iconographic conventions used by Justinian II.

Challenges and Failures

Philippicus’ most consequential failures related to the empire’s external security and to the domestic reaction his religious program provoked. While he diverted troops to strengthen the Balkans against a newly hostile Bulgarian ruler, the empire’s defenses in Asia Minor were left vulnerable. Arab commanders exploited this weakness and penetrated deep into Anatolia, sacking towns and wintering within imperial territory. These raids increased pressure on an overstretched military system and undermined confidence in central authority.

In the Balkans the Bulgar leader Tervel advanced to the outskirts of Constantinople, inflicting widespread plunder in the countryside. The transfer of veteran forces from Asia to Europe produced unrest among the troops, particularly within the elite Opsikion theme, whose officers resented the move and retained loyalty to competing factions. The religious changes that Philippicus enforced also generated sharp opposition abroad. The pope in Rome refused to recognize his ecclesiastical measures and took symbolic steps to exclude Philippicus from liturgical commemoration and from image programs, exacerbating the split between eastern and western Christian communities.

Domestically, Philippicus’ policies toward Armenians resident in imperial territory added to the controversy. He issued orders pressing Armenian Christians to accept the authority of the patriarch in Constantinople, a stance that prompted emigration among those who preferred their own ecclesiastical arrangements. Taken together, his theological assertiveness, the military strains caused by troop movements, and the political reconfiguration of elite patronage created a climate ripe for conspiracy.

Death and Succession

The end of Philippicus’ rule came in June 713 when officers associated with the Opsikion theme staged a coup. He was seized within the city and publicly blinded in the imperial hippodrome, a punishment that for an emperor marked an especially public and irreversible disqualification from office. The mutilation was followed immediately by the elevation of his chief secretary, Artemius, who took the throne under the name Anastasius II. Philippicus was removed to a monastic establishment and died in exile within a few months, his death recorded differently by later chronicles but generally placed shortly after his deposition.

The succession that followed his downfall did not restore long-term stability. Anastasius II’s own rule proved brief and contested, and the empire continued to be embroiled in military and theological conflicts. Philippicus’ violent overthrow thus formed one episode in a sequence of rapid changes of rulers that marked the early eighth century.

Legacy

Historical assessments of Philippicus are mixed, reflecting the brevity of his reign and the polarized nature of contemporary sources. Later chroniclers who opposed his theology condemned him as a heretical usurper, while a handful of local records and compendia portray him as a cultured patron who appealed to traditional aristocratic constituencies. His attempt to revive a conciliatory christological formula illustrates how theology and politics were intertwined in the early medieval imperial state, with doctrinal choices used to shape alliances and to win supporters in the eastern provinces.

Militarily, his rule is associated with an erosion of imperial security: Arab raids advanced deeper into Asia Minor and a Bulgar incursion reached the capital’s suburbs, events that signalled the empire’s vulnerability during a period of dynastic flux. Politically, his violent elevation and equally violent removal underline the fragility of legitimacy in a polity where military loyalties and ceremonial recognition by the church were decisive. Finally, his deposition introduced the use of blinding as a decisive means to bar a former emperor from returning to power, a method that would be reused in Byzantine politics thereafter.

In sum, Philippicus’ brief tenure altered the ecclesiastical landscape of his day and exposed structural weaknesses in imperial governance. His reign did not produce enduring reforms, but it did crystallize conflicts that shaped relations between Constantinople, Rome, and the various Christian communities of the Near East, while accelerating a pattern of rapid imperial turnover that would continue to affect Byzantium in the decades to come.
