Writing history was popular among Christian monks and clergy in the Middle Ages. They wrote about the history of Jesus Christ, that of the Church and that of their patrons, the dynastic history of the local rulers. In the Early Middle Ages historical writing often took the form of annals or chronicles recording events year by year, but this style tended to hamper the analysis of events and causes. An example of this type of writing is the "Anglo-Saxon Chronicle", which was the work of several different writers: it was started during the reign of Alfred the Great in the late 9th century, but one copy was still being updated in 1154. Some writers in the period did construct a more narrative form of history. These included Gregory of Tours and more successfully Bede, who wrote both secular and ecclesiastical history and who is known for writing the "Ecclesiastical History of the English People".
