Lord Byron (George Gordon Byron) joined the Greek War of Independence fighting the Ottoman Empire, for which many Greeks revere him as a national hero. He died in 1824 at the young age of 36 from a fever contracted while in Missolonghi. Often described as the most flamboyant and notorious of the English Romantics, Byron was both celebrated and castigated in life for his aristocratic excesses, including huge debts and numerous love affairs.

With his death, Byron's body was embalmed, but the Greeks wanted some part of their hero to stay with them. According to some sources, his heart remained at Missolonghi. His other remains were sent to England for burial in Westminster Abbey, but the Abbey refused for reason of "questionable morality".
