As Pierre Riché points out, the expression "Carolingian Renaissance" does not imply that Western Europe was barbaric or obscurantist before the Carolingian era.^[10] The centuries following the dissolution of the Roman Empire in the West did not see an abrupt disappearance of the ancient schools. Indeed, from them emerged Martianus Capella, Cassiodorus, and Boethius, essential icons of the Roman cultural heritage in the Early Middle Ages, thanks to which the disciplines of liberal arts were preserved.^[11] The 7th century saw the "Isidorian Renaissance" in the Visigothic Kingdom of Hispania^[12] in which sciences flourished^[13][14][15] and the integration of Christian and pre-Christian thought occurred,^[16] while the spread of Irish monastic schools (scriptoria) over Europe laid the groundwork for the Carolingian Renaissance.^[17][18]

There were numerous factors in this cultural expansion, the most obvious of which was that Charlemagne's uniting of most of Western Europe brought about peace and stability, which set the stage for prosperity. This period marked an economic revival in Western Europe, following the fall of the Western Roman Empire in the 5th century. Local economies in the West had degenerated into largely subsistence agriculture by the early 7th century, with towns functioning merely as places of gift-exchange for the elite.^[19] By the late 7th century, developed urban settlements had emerged, populated mostly by craftsmen, merchants and boaters and boasting street grids, artisanal production as well as regional and long-distance trade.^[19] A prime example of this type of emporium was Dorestad.^[19]

The development of the Carolingian economy was fueled by the efficient organization and exploitation of labor on large estates, producing a surplus of primarily grain, wine and salt.^[20][21] In turn, inter-regional trade in these commodities facilitated the expansion of towns.^[20][21] Archaeological data shows the continuation of this upward trend in the early eighth century.^[19] The zenith of the early Carolingian economy was reached from 775 to 830, coinciding with the largest surpluses of the period, large-scale building of churches as well as overpopulation and three famines that showed the limits of the system.^[22] After a period of disruption from 830 to 850, caused by civil wars and Viking raids, economic development resumed in the 850s, with the emporiums disappearing completely and being replaced by fortified commercial towns.^[22]

One of the major causes of the sudden economic growth was the Arab slave trade. Following the rise of the Arab Muslim caliphates, the Arab elites created a major demand for slaves in the Muslim world, with European slaves particularly prized. As a result of Charlemagne's wars of conquest in Eastern Europe, a steady supply of captured Slavs, Avars, Saxons, and Danes reached merchants in Western Europe, who then exported the slaves via Ampurias, Girona, and the Pyrenees passes to Muslim Spain and other parts of the Arab world.^[23] The market for slaves was so lucrative that it almost immediately transformed the long-distance trade of the European economies.^[24][25] The slave trade enabled the West to re-engage with the Arab Muslim caliphates and the Eastern Roman Empire, so that other industries, such as textiles, were able to grow in Europe as well.^[26]

Kenneth Clark was of the view that by means of the Carolingian Renaissance, Western civilization survived by the skin of its teeth.^[27] However, the use of the term renaissance to describe this period is contested, notably by Lynn Thorndike,^[28] due to the majority of changes brought about by this period being confined almost entirely to the clergy, and due to the period lacking the wide-ranging social movements of the later Italian Renaissance.^[29] Instead of being a rebirth of new cultural movements, the period was more an attempt to recreate the previous culture of the Roman Empire.^[30] The Carolingian Renaissance in retrospect also has some of the character of a false dawn, in that its cultural gains were largely dissipated within a couple of generations, a perception voiced by Walahfrid Strabo (died 849), in his introduction to Einhard's Life of Charlemagne,^{[n 1]} summing up the generation of renewal:

Charlemagne was able to offer the cultureless and, I might say, almost completely unenlightened territory of the realm which God had entrusted to him, a new enthusiasm for all human knowledge. In its earlier state of barbarousness, his kingdom had been hardly touched at all by any such zeal, but now it opened its eyes to God's illumination. In our own time the thirst for knowledge is disappearing again: the light of wisdom is less and less sought after and is now becoming rare again in most men's minds.^[32]

A lack of Latin literacy in eighth-century western Europe caused problems for the Carolingian rulers by severely limiting the number of people capable of serving as court scribes in societies where Latin was valued. Of even greater concern to some rulers was the fact that not all parish priests possessed the skill to read the Vulgate Bible. An additional problem was that the vulgar Latin of the later Western Roman Empire had begun to diverge into the regional dialects, the precursors to today's Romance languages, that were becoming mutually unintelligible and preventing scholars from one part of Europe being able to communicate with persons from another part of Europe.

To address these problems, Charlemagne ordered the creation of schools in a capitulary known as the Charter of Modern Thought, issued in 787.^[33] A major part of his program of reform was to attract many of the leading scholars of the Christendom of his day to his court. Among the first called to court were Italians: Peter of Pisa, who from 776 to about 790 instructed Charlemagne in Latin, and from 776 to 787 Paulinus of Aquileia, whom Charlemagne nominated as patriarch of Aquileia in 787. The Lombard Paul the Deacon was brought to court in 782 and remained until 787, when Charles nominated him abbot of Montecassino. Theodulf of Orléans was a Spanish Goth who served at court from 782 to 797 when nominated as bishop of Orléans. Theodulf had been in friendly competition over the standardization of the Vulgate with the chief among the Charlemagne's scholars, Alcuin of York. Alcuin was a Northumbrian monk and deacon who served as head of the Palace School from 782 to 796, except for the years 790 to 793 when he returned to England. After 796, he continued his scholarly work as abbot of St. Martin's Monastery in Tours.^[29] Among those to follow Alcuin across the Channel to the Frankish court was Joseph Scottus, an Irishman who left some original biblical commentary and acrostic experiments. After this first generation of non-Frankish scholars, their Frankish pupils, such as Angilbert, would make their own mark.

The later courts of Louis the Pious and Charles the Bald had similar groups of scholars many of whom were of Irish origin. The Irish monk Dicuil attended the former court, and the more famous Irishman John Scotus Eriugena attended the latter becoming head of the Palace School at Aachen.

One of the primary efforts was the creation of a standardized curriculum for use at the recently created schools. Alcuin led this effort and was responsible for the writing of textbooks, creation of word lists, and establishing the trivium and quadrivium as the basis for education.^[34]

Another contribution from this period was the development of Carolingian minuscule, a "book-hand" first used at the monasteries of Corbie and Tours that introduced the use of lower-case letters. A standardized version of Latin was also developed that allowed for the coining of new words while retaining the grammatical rules of Classical Latin. This Medieval Latin became a common language of scholarship and allowed administrators and travellers to make themselves understood in various regions of Europe.^[35]

The earliest concept of Europe as a distinct cultural region (instead of simply a geographic area) appeared during the Carolingian Renaissance of the 9th century, and included the territories which practiced Western Christianity at the time.^[36]

Carolingian workshops produced over 100,000 manuscripts in the 9th century, of which some 6000 to 7000 survive.^[37] The Carolingians produced the earliest surviving copies of the works of Cicero, Horace, Martial, Statius, Lucretius, Terence, Julius Caesar, Boethius and Martianus Capella.^[38] No copies of the texts of these authors were made in the Latin West in the 7th and 8th centuries.^[38]

According to Roger Wright, the Carolingian Renaissance is responsible for the modern-day pronunciation of Ecclesiastical Latin. Up until that point there had been no conceptual distinction between Latin and Romance; the former was simply regarded as the written form of the latter. For instance in early medieval Spain the word for 'century'—which would have been pronounced */sjeglo/— was properly spelled ⟨saeculum⟩, as it had been for the better part of a millennium. The scribe would not have read aloud ⟨saeculum⟩ as /sɛkulum/ any more than an English speaker today would pronounce ⟨knight⟩ as */knɪxt/ rather than /naɪt/.^[39]

Non-native speakers of Latin, however—such as clergy of Anglo-Saxon or Irish origin—appear to have used a rather different pronunciation, presumably attempting to sound out each word according to its spelling. The Carolingian Renaissance in France introduced this artificial pronunciation for the first time to native speakers as well. No longer would, for instance, the word ⟨viridiarium⟩ 'orchard' be read aloud as the equivalent Old French word */verdʒjǽr/. It now had to be pronounced precisely as spelled, with all six syllables: /viridiarium/.^[40]

Such a radical change had the effect of rendering Latin sermons completely unintelligible to the general Romance-speaking public, which prompted officials a few years later, at the Council of Tours, to instruct priests to read sermons aloud in the old way, in rusticam romanam linguam or 'plain roman[ce] speech' (while the liturgy retained the new pronunciation to this day).^[41]

As there was now no unambiguous way to indicate whether a given text was to be read aloud as Latin or Romance, and native Germanic speakers (such as church singers) numerous in the empire might have struggled to read words in Latin orthography according to Romance orthoepy, various attempts were made in France to devise a new orthography for the latter; among the earliest examples are parts of the Oaths of Strasbourg and the Sequence of Saint Eulalia. As the Carolingian Reforms spread the 'proper' Latin pronunciation from France to other Romance-speaking areas, local scholars eventually felt the need to create distinct spelling systems for their own vernaculars as well, thereby initiating the literary phase of Medieval Romance.^[42] Writing in Romance does not appear to have become widespread until the Renaissance of the Twelfth Century, however.^[43]

Carolingian art spans the roughly hundred-year period from about 800–900. Although brief, it was an influential period. Northern Europe embraced classical Mediterranean Roman art forms for the first time, setting the stage for the rise of Romanesque art and eventually Gothic art in the West. Illuminated manuscripts, metalwork, small-scale sculpture, mosaics, and frescos survive from the period.

Carolingian architecture is the style of North European architecture promoted by Charlemagne. The period of architecture spans the late eighth and ninth centuries until the reign of Otto I in 936, and was a conscious attempt to create a Roman Renaissance, emulating Roman, Early Christian and Byzantine architecture, with its own innovation, resulting in having a unique character.^[45] This syncretic architectural style can be exemplified by the first church of St Mark's in Venice, fusing proto-Romanesque and Byzantine influences.^[46]

There was a profusion of new clerical and secular buildings constructed during this period, John Contreni calculated that "The little more than eight decades between 768 to 855 alone saw the construction of 27 new cathedrals, 417 monasteries, and 100 royal residences".^[45]

Around AD 755, Charlemagne's father Pepin the Short reformed the currency of the Frankish Kingdom.^[47] A variety of local systems was standardized. Minor mints were closed and royal control over the remaining bigger mints strengthened,^[47] increasing purity.^[48] In place of the gold Roman and Byzantine solidus then common, he established a system based on a new .940-fine silver penny (Latin: denarius; French: denier) weighing 1/240 of a pound (librum, libra, or lira; livre).^[48] (The Carolingian pound seems to have been about 489.5 grams,^[49][50] making each penny about 2 grams.) As the debased solidus was then roughly equivalent to 11 of these pennies, the shilling (solidus; sol) was established at that value, making it 1/22 of the silver pound.^[51] This was later adjusted to 12 and 1/20, respectively. During the Carolingian period, however, neither shillings or pounds were minted, being instead used as notional units of account.^[48] (For instance, a "shilling" or "solidus" of grain was a measure equivalent to the amount of grain that 12 pennies could purchase.)^[52] Despite the purity and quality of the new pennies, however, they were repeatedly rejected by traders throughout the Carolingian period in favor of the gold coins used elsewhere, a situation that led to repeated legislation against such refusal to accept the king's currency.^[51]

The Carolingian system was imported to England by Offa of Mercia and other kings, where it formed the basis of English currency until the late 20th century.^[48]
