Henry XVI already had a dispute with Louis VII's father
Stephen III. On 17 April 1414, Henry and other enemies of Louis VII founded the
Parakeet Society. On 8 July 1415, the society was changed into the
League of Constance, an alliance for mutual defense against Louis VII. In 1417 in Constance, Louis insulted Henry by calling him "the son of a cook". When Louis then accused Henry of having shed human blood, Henry and fifteen of his followers physically attacked Louis and injured him severely. After this attack, Louis described Henry as a
pluethunt ("blood hound"), which did little to defuse the conflict. Henry XVI evaded punishment for the attack on Louis VII only through the intercession of
Frederick of Brandenburg and his cousins Dukes
Ernest and
William III in Munich and especially by paying 6000 guilders to King
Sigismund. Henry XVI wanted revenge. The conflict escalated into a war when an army from
Bavaria-Ingolstadt burned down the castle of the
Burgrave of Nuremberg.
John III, who had succeeded his brother
William II as Duke of
Bavaria-Straubing in 1418, remained neutral. ==Destruction==
