Sad news: the great Susan Reynolds has died, per Pauline Stafford on Twitter. Susan was the author of Kingdoms and Communities in Western Europe 900-1300 (1984), which I found very useful for my work. She was most famous for her book Fiefs and Vassals: The Medieval Evidence Reinterpreted (1994), which launched a great deal of discussion among medievalists about the concept of “feudalism” (i.e. “the f-word”), which she thought was essentially meaningless and should be eliminated from the historian’s vocabulary. She was also personally kind to me when I studied in London as an undergraduate and as a graduate student. Requiescat in pace.
