Arms of Edward III

This is the coat of arms of Edward III. When he claimed the French throne in 1337, he quartered the royal shield, combining the lions of England with the fleurs-de-lys of France.

Below are the arms of some of Edward's sons.

Arms of Edward III and Black Prince
Edward's eldest son was Edward, Prince of Wales (also known as the Black Prince).
Arms of Lionel Duke of Clarence
Edward's third son was Lionel of Antwerp (also known as Lionel, Duke of Clarence). He married Elizabeth, Countess of Ulster, in 1355.
Arms of John of Gaunt
Edward's fourth son was John of Gaunt (also known as John, Duke of Lancaster and King of Castile and Leon).
Arms of Edmund Duke of York
Edward's fifth son was Edmund of Langley (also known as Edmund, Duke of York).

Arms of Richard II

When displaying his arms, Richard II often combined the arms of St. Edward the Confessor (see the left half of the shield) to the arms used by Edward III (on the right half of the shield).

Arms of Henry IV

When Henry IV took the throne, he reverted back to the arms of Edward III but he reduced the number of fleurs-de-lys to three in each quarter.
