History of Constans II

Constans II, also known as Constans II Pogonatus, was an emperor of the Byzantine Empire whose reign is notable for the significant challenges he faced, both internally and externally. Born Heraclius Constantine on November 7, 630, he ascended to the throne as a child co-emperor in 641 and later as the sole emperor after tumultuous beginnings, his reign extended until his assassination in 668. His governance was marked by a series of complex political maneuvers that helped shape the future of the Byzantine state.

Constans II's early reign was molded by the legacy of his grandfather, Emperor Heraclius, who had struggled against both the Sasanian Persians and the rise of Islam in the Arabian Peninsula. Heraclius’s efforts left behind an empire weakened by years of warfare and vulnerable to the expanding Muslim Caliphate. This pressure from the Islamic forces presented one of the foremost challenges to Constans during his rule.

Upon taking power, Constans was immediately thrust into the political maelstrom of the Byzantine Empire. His ascension to the throne came after the death of his father, Constantine III, and the subsequent power struggle that saw his uncle Heraklonas briefly seize control. The political elite within Constantinople quickly restored Constans as emperor, marking the beginning of his lengthy reign.

A significant threat during Constans's tenure was the advancing Muslim forces, who capitalized on the weakened state of the Byzantine Empire to make significant territorial gains. Constans II’s attempts to repel Islamic advances were largely defensive; he fortified cities, reorganized the military, and enacted strategic retreats when necessary. Nonetheless, substantial losses occurred, including the important city of Alexandria in 642 and parts of Armenia by 650. One of Constans's major military engagements was the campaign against the Arabs in the Mediterranean, intending to secure Byzantine claims over key islands like Sicily and Malta and to safeguard maritime routes from Muslim sieges.

Aside from external threats, Constans II confronted internal dissent and theological disputes that threatened to fracture the empire from within. The religious unrest primarily stemmed from the ongoing doctrinal debates over Monothelitism, a Christological doctrine proposing that Christ had two natures but only one will. This doctrine was seen as a potential compromise between the orthodox Chalcedonian Christology and the Monophysites. Constans initially sought to uphold this doctrine, thinking it would create unity within the divided church. However, his issuance of the Typos in 648, an edict that sought to end disputes by forbidding discussion of the wills of Christ, only served to exacerbate tensions. This religious stance alienated a significant portion of the clergy, including the pope, further complicating Byzantium’s ecclesiastical politics.

One of Constans II's most controversial decisions was his choice to move the imperial capital from Constantinople to Syracuse in Sicily in 663. This decision highlighted his strategic focus on the western territories of the empire, perhaps driven by the need to secure these regions against Muslim advances and consolidate his authority against the decentralized provincial elites. However, the move was unpopular among Constantinopolitans, who viewed it as abandonment.

The decision to relocate the capital also reveals Constans’s focus on Italy and the broader western affairs of the empire. He engaged in military campaigns to defend Byzantine holdings in Italy against the Lombards, an endeavor that underlined his commitment to maintaining Byzantine influence in the West. This also demonstrates Constans’s intricate power play, attempting to balance between defending against external threats and securing his internal position by maintaining influential bases in the west.

Constans’s reign was abruptly ended when he was assassinated in 668 while taking a bath—or so legend has it. His demise was orchestrated by court officials, which underscored his unpopular policies and perhaps the dissatisfaction stemming from his controversial relocation to Syracuse. Following his death, his son, Constantine IV, ascended to the throne, tasked with the challenge of securing an empire still reeling from his father's arduous and often troubled reign.

Constans II’s reign, while marred with military and religious conflicts, nonetheless played a critical role in shaping future Byzantine policies. His efforts at centralization, military reorganization, and his handling of religious controversies, albeit controversial, laid a foundation that subsequent emperors would build upon. Constans II’s historical legacy is that of a ruler confronted with overwhelming challenges, striving however imperfectly to preserve an empire caught in the throes of transition—from the old Roman to the medieval Byzantine world.
