Why are you a historian of medieval Europe? 

The Middle Ages are the goldilocks period: enough sources that discoveries remain possible, but not so many that you lose perspective.

What’s the most important lesson history has taught you? 

That people at any given time are unlikely to be good judges of what’s really going on (and why).

Which history book has had the greatest influence on you? 

Geoff Koziol’s Politics of Memory and Identity in Carolingian Royal Diplomas.  

What book in your field should everyone read? 

Janet L. Nelson’s Charlemagne: King and Emperor.

Which moment would you most like to go back to?

When Henry I was elected king of Germany in 919.

Simon Keynes.

How many languages do you have?

Is there an important historical text you have not read? 

Lots! I haven’t read many sources from later than the 12th century.

What historical topic have you changed your mind on? 

I used to doubt that the changes undergone in western Europe’s ‘feudal revolution’ were substantial; now, I’m inclined to accept that they were.

Which person in history would you most like to have met? 

Æthelred ‘the Unready’. I’ve always been inclined to look kindly on him, despite (or indeed perhaps on account of) his poor reputation.
