Which 789 capitulary issued by Charlemagne promoted church and educational reform?

The 789 capitulary issued by Charlemagne to promote church and educational reform was the Admonitio generalis, or General Admonition. It formed a central part of Charlemagne's effort to create a disciplined, Christian, and better-administered Frankish kingdom.

The document addressed the conduct and education of clergy, the correction of religious practice, and the moral responsibilities of Christian communities. It called for monasteries and cathedrals to establish schools where boys could learn reading, writing, grammar, singing, and psalmody. These measures were intended to improve the clergy's ability to understand and transmit biblical and liturgical texts accurately.

The capitulary also reflected Charlemagne's belief that royal authority had a responsibility for the spiritual welfare of his subjects. It presented him in the role of a ruler working to reform the Christian community, an idea often connected with the biblical King Josiah. The reforms helped drive the wider Carolingian Renaissance.

The Admonitio generalis is sometimes confused with later legislation, such as the Constitutio Romana, or with unrelated ancient texts such as the Edict of Milan. Those documents had different dates, purposes, and political contexts.
