His "Dwie drogi" (Two ways, 1959) about the January Uprising of the 1860s represent the latest historical period he has tackled. His other popular historical books include "Trzej kronikarze", (Three chroniclers; 1964), a book about three medieval chroniclers of Polish history (Thietmar of Merseburg, Gallus Anonymus and Wincenty Kadłubek), in which he discusses the Polish society through ages; and "Ostatnia z rodu" (Last of the Family; 1965) about the last queen of the Jagiellon dynasty, Anna Jagiellonka. His "Rozważania o wojnie domowej" (1978; Thoughts on Civil War) were the last book he has finished; unlike the majority of his other works, this book is ostensibly about the civil war (Chouannerie) in Brittany, France. This work does however contains numerous arguments applicable to more modern Polish history; arguments that Jasienica thought would not be allowed by the censors if the book discussed Polish history.
