Indicated an age of German Nationalism led to World War II

Napoleon Bonaparte made the decision to engage the alliance of European Armies that had been established against him after regaining control in 1815.

Field Marshal Gebhard led the Prussian army, while Field Marshal Field was in charge of the British army. The Prussian state's mythology preserved the role the Prussian Army played in defeating the French Army at Waterloo.

By fostering nationalism, mythology was a key factor in the formation of the new German Empire (1870). Hyper-nationalism sprang from nationalism and gave rise to the Nazi party.

The Third Reich and World War II were caused by the development of the Nazi party, a German hyper-nationalist party. This indicated an age of German Nationalism led to World War II, so it is one of the best significance of the battle of Waterloo.
