What happens when charlemagnes dies?

Charlemagne died on January 28, 814. His death led to the fragmentation of his vast empire, as it was divided among his three grandsons, leading to internal conflicts and struggles for power. This division weakened central authority and paved the way for the eventual rise of feudalism in Europe. His death also marked the decline of the Carolingian Empire, as it struggled to maintain unity and stability in the years that followed.
