Lions and a unicorn appear on Prince Harry's coat of arms; these are the only animals to appear on this emblem. Queen Elizabeth authorized Prince Harry to receive a personalized coat of arms for his 18th birthday. Prince Harry was personally involved with the design process.
Prince Harry's personal coat of arms is based on traditional designs relating to emblems representing the British monarchy. Other sources of aesthetic inspiration include the coat of arms belonging to his older brother, Prince William. The coat of arms also includes imagery alluding to the family lineage of Prince Harry's mother, Lady Diana Spencer.
