From Wikipedia: The Order of the Holy Spirit was an Order of Chivalry under the French Monarchy. All Knights of the order were also members of the Order of Saint Michael. The symbol of the order is known as the Cross of the Holy Spirit. This is a Maltese Cross (i.e. a cross formed by the meeting for the points of four isosceles triangles); at the periphery, the points of each triangle are rounded, and between each triangle there is a fleur-de-lis. Imposed on the centre of the cross is a dove. The eight rounded corners represent the Beatitudes, the four fleur-de-lis represent the Gospels, the twelve petals represent the Apostles, and the dove signifies the Holy Spirit.

During the French Revolution the Order of the Holy Spirit was officially abolished by the French government along with all other chivalric orders from the Ancien Regime, although the exiled Louis XVIII continued to acknowledge it. Following the Restoration, the order was officially revived, only to be abolished again by the Orleanist Louis-Philippe following the July Revolution in 1830. However, the Legitimist pretenders to the French throne have continued to nominate members of the order, long after the abolition of the French monarchy itself.
