Passage fee is a donation given by a newly dubbed knight in celebration of his investiture into the knighthood. During the Crusades, passage fees, known as droit de passage, were used to cover the cost of travel to the Holy Land. The passage fee is still present in some modern organisations, including the Order of the Holy Sepulchre.
