旗幟
Upon his succession to the throne, Willem-Alexander adopted the Royal Standard of the Netherlands, which is a square orange flag, divided in four-quarters by a nassau-blue cross. All quarters show a white and blue bugle-horn, taken from the coat of arms of the Principality of Orange. In the centre of the flag is the (small) coat of arms of the Kingdom, which originates from the arms of the House of Nassau, surmounted by a royal crown and surrounded by the insignia of the Grand Cross of the Military William Order.
