Is king david related to Charlemagne?

King David and Charlemagne are not directly related, as they lived in different historical periods and belonged to different lineages. King David, a biblical figure, reigned around 1000 BCE in ancient Israel, while Charlemagne, a medieval emperor, ruled much later, from 768 to 814 CE in what is now France and Germany. However, both figures are significant in their respective cultures and histories, with David being a key figure in Jewish history and Charlemagne in European history. Any connection would be more about historical legacy than a direct familial relationship.
