The Kingdom of Hungary was a vast realm, at least the size of France, that endured throughout the Middle Ages whilst the Byzantine Empire was even more extensive and enduring. The Serbians won themselves a brief but extensive local empire in the 14th century; while the Bulgarians established an effective and cultured state. Other players in the confusing Balkan scene included the Albanians; Wallachians; Moldavians; Transylvanians; Croatians and many others. How did they organise their armies and fight their wars; and why did they ultimately fail? This title answers these questions ably supported by numerous illustrations and eight colour plates.
