Despite intensive research on late Roman and Byzantine diplomatic and military history since the last decades of the 19th century, scholars had to wait until the year 2001 for the first monograph which deals exclusively with the foederati. The author, Ralf Scharf (S.), questions commonly held views and offers an original interpretation of the evolution of the foederati stretching from the Roman West of the early 5th century ce to Asia Minor in the 11th century. The book includes an introduction, (...) nine chapters, a conclusion, a bibliography, an index locorum (unfortunately not exhaustive) and a general index. (shrink)
