What happened after Charlemagne put down the uprising in rome?

After Charlemagne put down the uprising in Rome, he solidified his control over the city and strengthened his alliance with the papacy. He restored Pope Leo III to power, who had been attacked by rival factions, thereby reinforcing the church's influence and Charlemagne's legitimacy as a ruler. This event also marked a significant step in the establishment of the Carolingian Empire and the relationship between the Frankish kings and the papacy, laying the groundwork for the eventual Holy Roman Empire. Charlemagne's actions helped to promote a sense of unity in Christendom during the early Middle Ages.
