The book by a modern English historian gives a new interpretation of the image of one of the most famous monarchs, whose reign occurred in the first half of the 15th century. Under the pen of D. Seward, Henry V appears not just as a trivial tyrant, but also as a talented diplomat and commander. This study gives a fairly clear idea of the personality of the English king against the background of the turbulent events of a distant era, and brings the reader closer to the solution to the “phenomenon” of Henry V.
