The Crusade of 1197, also known as the Crusade of Henry VI or the German Crusade, was a crusade launched by the Hohenstaufen emperor Henry VI in response to the aborted attempt of his father, Emperor Frederick I, during the Third Crusade in 1189–90.
Thus the military campaign is also known as the "Emperor's Crusade".
