The Thirty Years War was a series of conflicts that ravaged large areas of Europe, especially the German provinces, from 1618 to 1648. These conflicts centred on the Habsburg Holy Roman Emperors, Ferdinand II and Ferdinand III, and their opponents. Although viewed by many as a religious war between Catholic and Protestant nations, its roots and causes were also politically motivated. The combination of religious fervour and the political ambition of the European superpowers were to pit vast armies and mighty leaders against each other. The devastation caused by decades of fighting had truly turned Europe into the 'Devil's Playground'. This supplement for Pike & Shotte describes the history, armies, personalities and battles of the Thirty Years War. Included are scenarios based on some of the famous battles and army lists for the main protagonists. A copy of the Pike & Shotte rulebook is required to use this supplement.
