Charlemagne, also known as Charles the Great, was king of the Franks and later emperor of the Holy Roman Empire from 768-814 AD. He had a significant impact on the history of the Christian church in Western Europe through his military conquests, promotion of education and literacy, and relationships with the papacy.
Military Conquests and Christianization Efforts
As a military ruler, Charlemagne led campaigns to conquer and Christianize pagan Germanic tribes. In the late 8th century, he waged wars against the Saxons in northern Germany over several decades. The Saxons practiced Germanic paganism, which Charlemagne sought to supplant with Christianity. To achieve this goal, he forcibly baptized Saxons and enacted laws requiring Christian practices. Charlemagne’s efforts against the Saxons were brutal at times, including mass executions of those who refused baptism. While these methods raise ethical concerns today, they were part of a strategy to spread Christianity in medieval Europe. By 804, the Saxon Wars ended with the Saxons’ conversion to Christianity.
Charlemagne waged similar campaigns against pagan peoples like the Avars and Slavs in eastern Europe. He used his military power to destroy pagan temples and idols and established political control over these territories. Once conquered, he sent bishops, priests, and missionaries to Christianize local populations through preaching, education, and the establishment of churches and monasteries. While violent at times, these conquests did succeed in expanding Christianity into Central and Eastern Europe.
Promotion of Education and Literacy
Charlemagne saw education and literacy as vital to strengthening Christianity in his empire. Most people in western Europe at this time were illiterate, including many clergy. To improve literacy, Charlemagne issued decrees calling on monasteries and churches to establish schools to provide religious education. He imported scholars from England and Ireland to serve as teachers in Francia. Charlemagne himself studied rhetoric, astronomy, arithmetic, grammar and music.
Charlemagne also instituted educational reforms for the clergy. He commanded monks and priests to learn to read and write Latin, and required convents and monasteries to maintain libraries of Christian volumes. Priests were expected to be able to preach, teach, and explain Scripture to the laity. By improving education for clergy, Charlemagne enabled them to be more effective evangelists and teachers to the broader population.
Additionally, Charlemagne commissioned new copies of Christian texts and helped standardize monastic scribal writing. He imported texts from Rome and urged the creation of Frankish illuminated manuscripts – Christian books decorated with illustrations. Improved book production helped transmit Christian teachings and Bible commentary.
Relationship with the Papacy
As ruler of the expanding Frankish kingdom, Charlemagne forged an important political and religious bond between his empire and the papacy in Rome. In 800 AD, Pope Leo III crowned Charlemagne emperor in Rome, forming the political-religious entity of the Holy Roman Empire. The coronation created a partnership whereby the pope exercised spiritual authority over Western Christendom, while Charlemagne provided military protection and secular leadership.
This joining of secular and ecclesiastical power did not subvert the pope’s authority over the Western church. Charlemagne saw protection of the church as one of his imperial duties. He provided donations of money and land to Rome and other bishoprics. He also enacted laws upholding church doctrines and suppressing heresy and paganism in his domains.
The Carolingian Renaissance, a period of cultural and intellectual flourishing encouraged by Charlemagne, also strengthened connections between Frankish and papal Rome. Charlemagne oversaw the compilation of Christian writings, biblical commentaries, and records of church councils and synods, helping reinforce Roman Catholic orthodoxy in the Frankish church.
Preservation of Papal Authority in Rome
A significant event late in Charlemagne’s reign was his affirmation of papal authority in Rome. In 799, Pope Leo III was violently attacked by rivals, who sought to blind and depose him as pontiff. Leo fled to Charlemagne, who traveled to Rome and reinstated Leo as pope.
Charlemagne then presided over a council that investigated Leo’s conduct. The council found Leo innocent of wrongdoing and reaffirmed his position as leader of the church. Through his actions, Charlemagne protected the pope against forces trying to undermine papal authority in Rome. This event helped solidify a tradition of legal emperor-pope relations that influenced Western Europe for centuries.
Promotion of Roman Catholic Unity
Charlemagne used his secular power to enforce uniformity in Christian belief and worship throughout his empire. His goal was to unite the Frankish church and thereby all Western European Christianity under Roman Catholicism centered in Rome.
To accomplish unity, Charlemagne denounced local Christian traditions he viewed as erroneous. He condemned adoptionism in Spain, which held Jesus was born a man and became divine later. He also opposed forms of Christianity deeming icons and saint veneration as idolatry.
Charlemagne convened the Council of Frankfurt in 794, which officially repudiated adoptionism and iconoclasm as heresies. The council asserted the Roman Catholic position that Jesus was eternally divine and that icons deserved veneration but not worship. Charlemagne coerced Spanish and Frankish clerics to accede to Catholic orthodoxy and excommunicated those refusing.
Through these acts, Charlemagne strengthened the bonds of religious belief and practice between Rome, his empire and Western Europe. This contributed to the dominance and standardization of Roman Catholicism for centuries thereafter.
Impact on the Papacy as a Political Institution
As emperor, Charlemagne elevated the political power and prestige of the papacy throughout Western Christendom. Pope Leo III’s coronation of Charlemagne established the pope’s right to select and ordain emperors. This imbued future popes with new authority as kingmakers conferring imperial legitimacy on rulers.
The emperor-pope bond Charlemagne forged also gave the papacy greater voice in administering temporal affairs. Succeeding popes called upon Frankish rulers to provide military support in times of conflict. The precedent of Charlemagne defending Leo III from Roman rivals later emboldened popes to request aid defending church prerogatives.
In the centuries after Charlemagne, struggles between emperors and popes caused the emperor-pope relationship to fluctuate. However, the partnership inaugurated by Charlemagne definitively shaped conceptions of the pope as a powerful secular ruler alongside his spiritual authority.
Promotion of the Cult of Saints
Charlemagne played an important role in promoting the cult of the saints in Western Europe. He sought to unify his empire not just through Roman Catholicism but also devotion to shared Christian holy figures.
Throughout his lands, Charlemagne elevated local saints that proved popular with common people, granting official recognition of stories of their holy lives and miracles. He donated lavish gifts to saints’ shrines to encourage pilgrimage. Some of the saints he promoted included St. Martin of Tours in Francia and St. Peter in Rome.
Charlemagne also collected saints’ relics – physical remains or items associated with holy figures. He presented these relics, encased in precious gems and metals, to churches and monasteries, further stimulating veneration. By encouraging shared devotion to saints across his empire, Charlemagne strengthened cultural bonds that complemented Roman Catholic unity.
This focus on saints created a religious fervor around holy figures credited with healing powers and other blessings. The zeal for saints Charlemagne stimulated shaped popular religious piety in Western Europe for centuries and became a defining trait of medieval Christianity.
Standardization of Church Liturgy and Music
In his drive to unify Christian practice, Charlemagne sought to standardize the liturgy and church music throughout his empire. He saw variation in prayers, mass rites, and church songs as detrimental to spiritual unity.
Around 789, Charlemagne’s palace scholar Alcuin produced a unified liturgical book specifying required prayers, readings, and mass procedures for the Frankish church. Charlemagne then ordered bishops and abbots to ensure church services strictly followed this liturgy. Any variations were condemned as illegitimate. This was the first major move to standardize liturgy in the West.
Additionally, Charlemagne imported Roman clerics to train Frankish cantors in plainsong – monophonic, chant-based sacred music. He commanded all churches to perform this Roman style of singing at services rather than local polyphonic styles. By uniformizing church music as well as liturgy, Charlemagne tightened bonds between Rome and Franks.
Charlemagne’s liturgical and musical reforms proved long-lasting. Later Roman Catholic rites standardized across Europe by Pope Gregory VII in the 11th century were based largely on models mandated by Charlemagne centuries before.
Legacy as a Christian Emperor
As the first emperor crowned by the pope, Charlemagne has been celebrated through history as the archetypal Christian monarch. For medieval and Renaissance Europe, he represented the ideal blending of secular government and spiritual guardianship of Christendom. Even in later centuries, many Western rulers looked to his model of sacred kingship.
Charlemagne’s military conquests on behalf of Christianity, his protection and reverence for the Roman church, and his use of imperial power to spread and enforce the faith throughout Europe established him as the champion par excellence of medieval Roman Catholicism.
For these reasons, Charlemagne is regarded as a founding father of Christian Europe. His crowning made him a living symbol of the spiritual unity of Western Christendom under papal authority – a unity he forcefully pursued through reform, education, conquest and suppression of religious diversity. The Holy Roman Empire inaugurated by Charlemagne unified much of Western Europe around Roman Catholicism for nearly 1,000 years after his death.
