This set is an excellent companion to J. R. Strayer's edited Dictionary of the Middle Ages (CH, Nov'87; Supplement I, ed. by W. C. Jordan, CH, Sep'04, 42-0044). The focus on warfare allows the editors to offer larger entries on major topics (e.g., "Agincourt," "Crusades," "Feudalism") and introduce many complementary topics. The editors are concerned with Europe; they expand coverage into Asia or Africa only because of the connection to medieval Europe. Coverage also includes an abundance of entries pertaining to Central and Eastern Europe. Most of the 1,000-plus entries are about a page in length, but a few approach 50 pages. Medium and large-size entries, such as "Chivalry," "Germany," and "Slavic Lands," discuss primary sources and very valuable historiographies. A thorough index helps readers locate the Knights Templar under "Orders, Military, Levantine Orders." Cross-references and bibliographies follow each of the signed entries. Locating reliable and scholarly information on the Knights Templar and Vlad Tepes (Dracula) is tricky. Some of the bibliographies include sources in foreign languages. For example, the references for the Black Army of Hungary are in Hungarian. Noticeably missing are entries for the many wars. This set is particularly suited to research libraries. Summing Up: Highly recommended. Lower-level undergraduates through professionals/practitioners; general readers.
