I have a follow-up question to this as well, specifically in relation to England. I've done some coursework on the subject of the Carolingian monarchy, and was wondering what made Anglo-Saxon churchmen (Alcuin of York, St. Boniface, etc) so prolific in their attempts to expand Christianity across the continent, was it their (relatively) recent re-christianization, or some other feature of the Insular way of life. While for the most part, it seems that "Insular" implied a separate culture apart from the continental Roman and Carolingian culture (from differences in scripts), it also seems that Charlemagne relied on the help of English clergy as a sort of think tank to develop the Christian community in his kingdoms. What made the Carolingian clergy unable to do this, or rather what made the English the right fit for the job?

I apologize if this isn't in the right place, with the rules about top level comments, this is my first post on this sub, and a topic I have a lot of interest in so I just wanted to get it out there. Another disclaimer being that I am not a historian, just a student in an unrelated field who took an elective, so if I have misinterpreted anything in the sources, let me have it!
