On May 30, 1431, during the Hundred Years' War, 19 year old Joan of Arc was burned at the stake by an English-dominated tribunal in Rouen, France. From the article:
"Death
On May 29, 1431, the tribunal announced Joan of Arc was guilty of heresy. On the morning of May 30, she was taken to the marketplace in Rouen and burned at the stake, before an estimated crowd of 10,000 people. She was 19 years old. One legend surrounding the event tells of how her heart survived the fire unaffected. Her ashes were gathered and scattered in the Seine.
Retrial and Legacy
After Joan's death, the Hundred Years’ War continued for another 22 years. King Charles VII ultimately retained his crown, and he ordered an investigation that in 1456 declared Joan of Arc to be officially innocent of all charges and designated a martyr. She was canonized as a saint on May 16, 1920, and is the patron saint of France."
