Prince Leopold, Duke of Clarence

Prince Leopold (the widower of George IV's daughter, Princess Charlotte, who tragically died in 1817) appeared in full Garter Robes. Prince Leopold, as a foreign prince, was not entitled to wear any British Robes of Estate.

Henry Rivington Hill, who watched the procession to the Abbey, wrote that;

"With the exception of the King, Lord Londonderry and Prince Leopold were the most conspicuous figures in the procession. They were the only two habited in the full dress of a Knight of the Garter, the other Knights of that Order being also Peers and dressed accordingly. Lord Londondarry, not being a peer (of Great Britain), walked alone, carrying in his hand a black velvet Spanish hat with an immense plume of white ostrich feathers ..."

The Duke of Clarence (later William IV) wore as a Peer of the Realm his Robes of Estate including a duke's coronet and red velvet mantle trimmed with ermine.
