What was the Carolingian revival?

The Carolingian Renaissance occurred during the 7th century, in the wake of the Merovingian Dynasty, under the rule of Frankish emperor Charlemagne (768-814.) Most noteworthy is the revival of classical learning during this time period.
During the Merovingian Dynasty, the scola palatine, or palace school, held the responsibility of educating Frankish nobles in subjects related to politics. Other subjects—mainly literature—remained the role of the monastic schools. Under Charlemagne’s rule, the responsibilities held by the scola palatine increased, as part of a larger, overarching educational reform both within and outside of the Church. With this reform came a new head of the palace school, an English monk, Alcuin of York.
The intellectual schooling of clergy was considered rather daring for the time period. But Charlemagne maintained that the clergy must learn proper Latin syntax, for example, in order to properly understand scripture. Classical authors were studied in addition to Christian scripture, giving particular attention to the style in which they were written: grammar, rhetoric, and dialectic (also known as Boethius’s Trivium). Scientific subjects, including arithmetic, astronomy, music, and geometry, were taught to more advanced students.
Perhaps the most notable of his reforms was Charlemagne’s all-inclusive approach to education, allowing students outside of the clergy access to the same schooling as clergy members. In fact, a reported increase in literacy of the lay (non-clergy) population gives credence to his claims of the importance of proper language usage. Many manuscripts written by Carolingian scholars have survived to this day. This is likely due to the fact that students were encouraged to write their own content, rather than simply copying manuscripts, a common educational practice of the time period. The Frankish court became a sort of hub for scholars and writers even into the tenth century, likely a direct result of the Carolingian Renaissance.

The Carolingian revival, or Carolingian Renaissance, was a period of cultural renewal during the reign of the emperor Charlemagne in the 7th century. The purpose of the revival was to foster unity and stability in Charlemagne's empire in an attempt to emulate the glory of the ancient Roman Empire. The Carolingian Renaissance was largely the work of a circle of educated men in Charlemagne's court who composed literary and theological works, standardized a new style of writing (Carolingian miniscule), and experimented with new architectural and artistic styles. One of the major goals of the revival was to promote Latin literacy among clergy and government officials. Although at first limited to Charlemagne's inner circle, the Carolingian Renaissance eventually radiated outward to other areas of the empire and had far-reaching influence on European culture, preparing the way for the cultural achievements of the high Middle Ages and the Renaissance.
