The Teutonic Knights were one of the great chivalric orders that emerged from the Crusades, alongside the Hospitallers and Templars. The Teutonic Knights evolved out of a "fraternity" of German crusaders who took part in the siege of Acre during the Third Crusade. 'Help, defend, Heal' was the motto of the 'Order of Brothers of the German House of Saint Mary in Jerusalem', the Teutonic Order. It was formed to aid Christians on their pilgrimages to the Holy Land and to establish hospitals.
