Ich Dien

The Prince of Wales's feathers is the heraldic badge of the Prince of Wales. It consists of three white ostrich feathers emerging from a gold coronet. A ribbon below the coronet bears the motto Ich dien ([ɪç ˈdiːn], German for "I serve"). As well as being used in royal heraldry, the badge is sometimes used to symbolise Wales, particularly in Welsh rugby union and Welsh regiments of the British Army.

The badge has no connection with the native Princes of Wales.

Its use is generally traced back to Edward, the Black Prince (1330–1376), eldest son and heir apparent of Edward III of England. Edward bore (as an alternative to his differenced royal arms) a shield of Sable, three ostrich feathers argent, described as his "shield for peace": this probably means it was the shield he used for jousting. These arms can be seen several times on his tomb chest in Canterbury Cathedral, alternating with his royal arms. The prince also used badges of one or more ostrich feathers in a number of other contexts.

The feathers had first appeared at the marriage of Edward III to Philippa of Hainault, and it is therefore likely that the Black Prince inherited the badge from his mother. Philippa was descended from the Counts of Hainault, whose eldest son bore the title "Count of Ostrevent", the ostrich (French: autruche, Old French spellings including ostruce) feathers being (perhaps) a heraldic pun on that name. Alternatively, the badge may have derived from the Counts of Luxembourg, from whom Philippa was also descended, and who had used the badge of an ostrich.
