The Equestrian Events at the 1952 Helsinki Summer Olympics included Dressage, Eventing, and Show Jumping. All three disciplines had both individual and team competitions. The competitions were held from July 28, 1952 to August 3, 1952.
One of the biggest changes at the 1952 Olympics was the demographics of competitors. Before this, most of the riders were officers (41 of 44 starters at the 1948 Olympics were riding in uniform), whereas the Helsinki Games saw over 50% of competitors from the civilian ranks. Additionally, women were now allowed to compete for the first time in equestrian events. At the 1952 Games, they were permitted in the dressage competition, although prohibited from the jumping (per a ruling in 1951) and most definitely not in eventing which was considered too dangerous. The United States had to drop one of their show jumping riders after the ruling in 1951 because she was a woman. A total of 4 women competed out of 138 riders.
25 nations competed: Argentina, Brazil, Bulgaria, Canada, Chile, Denmark, Egypt, Finland, France, Federal Republic of Germany, Great Britain, Ireland, Italy, Japan, Korea, Mexico, the Netherlands, Norway, Portugal, Rumania, Soviet Union, Spain, Sweden, Switzerland, and the USA. This was the first appearance for Canada, Egypt, Korea, and the Soviet Union. Russia had sent riders to the 1912 Games, but had not competed since, and the Soviet Union performed poorly at the 1952 Games because they had been isolated from the rest of the world for over 35 years. This disadvantage did not last long, with the Soviet Union winning dressage gold a few years later. The youngest participant was Walter Staley from the United States at 19 years old, while the oldest rider was the Danish Kristian Jensen at 63 years old.
52 riders from 20 nations competed at the 1952 Games. For the first time, individual and team medals were awarded based on a two-round Prix des Nations (Nations Cup). 16 teams rode around Björn Strandell's 786 meter course with a 1 min 57.2 second time allowed and fences up to 1.60 meters in height and a 5-meter water jump. The individual gold was won by the French rider Pierre d'Oriola, aboard the gelding, Ali Baba. D'Oriola would repeat the feat in 1964 and remains the only rider to win two gold medals in this discipline. The team event was won by Great Britain, anchored by a clear round for Harry Llewellyn and Foxhunter. This gold medal, attained on the last day of competition, was Great Britain's only gold of the 1952 Games. They remain the only nation to have won gold medals in every Summer Olympics since 1896.
