John the Fearless spent most of his time and his considerable political and military energies in France, Paris being his normal place of residence and seat of government.
Before his accession to the Duchy of Burgundy, John was one of the principal leaders of the French forces sent to aid King Sigismund of Hungary in his war against Sultan Bayezid I. John fought in the Battle of Nicopolis of 25 September 1396 with such enthusiasm and bravery that he was given the cognomen Fearless (Sans-Peur).
