Her favorite horse was called Burmese. She was a regal black mare, given to Queen Elizabeth II by the Royal Canadian Mounted Police. The Queen rode her for 18 consecutive years, from 1969 to 1986, including during Ronald Reagan’s 1982 visit to Windsor Castle. (The president was lent Centennial, a black gelding, for the occasion.)

The Queen’s love of horses started early. Born in 1926, she had her first riding lesson at the age of three, and received her first pony, a Shetland mare, the following year—a fourth-birthday present from her grandfather King George V. At 11, when a reporter asked her what she wanted to be when she grew up, the future Queen answered (“without a moment’s hesitation,” according to Life magazine), “I should like to be a horse.”
