King Edward VIII was the United Kingdom's shortest-reigning monarch, having abdicated 11 months after succeeding to the throne so that he could marry American divorcee Wallis Simpson. After his abdication he was created Duke of Windsor.

As king, Edward bore the UK arms which have existed since the accession of Queen Victoria in 1837.

Edward was originally granted arms after being created Prince of Wales in 1911. These were the royal arms differenced by a plain white label of three points, the traditional arms of the heir apparent, but for the first time an inescutcheon (small shield in the middle) was added containing the arms of Wales and ensigned with the Prince of Wales's coronet.

After his abdication, the Duke of Windsor was granted the royal arms differenced by a white three-pointed label with a royal crown on the middle point.
