The Order of the Belt of Hope was a knighthood order which was founded in 1389 by King Charles VI of France and dedicated it to "Our Lady who bring back home the lost hunters".
Other sources including Menestrier named Louis II, Duke of Bourbon as founder, maybe making a mistake with the Order of Our Lady of the Thistle.
Ackermann mentions this chivalric order as historical order of France.
