Princess Anne has had an epic career as an equestrian. In fact, she is the first member of the royal family to have competed in the Olympics.
The now 69-year-old won two silver medals and one gold medal at the European Eventing Championships in the 70s', according to Express.
In the upcoming season of The Crown, Princess Anne will be dressed in equestrian gear often to highlight her horse roots.
What's more, her Royal Highness met her second husband, Sir Timothy Lawrence, through her career, as he served as the Queen's equerry between 1986 and 1989.
Princess Anne's daughter Zara Tindall followed in her mother's footsteps by pursuing a career as an equestrian as well.
The 38-year-old won the Eventing World Championship in Aachen in 2006 as well as a silver medal in the 2012 Summer Olympics. The Princess Royal presented her with the medal.
Zara was also appointed Member of the Order of the British Empire in 2007 for her services to equestrianism.
