Women's sports includes amateur as well as women's professional sports, in virtually all varieties of sports. Female participation in sports rose dramatically in the twentieth century, especially in the last quarter, reflecting changes in modern societies that emphasized gender parity. Although the level of participation and performance still varies greatly by country and by sport, women's sports have broad acceptance throughout the world in the 2010s. In a few instances, such as figure skating, women athletes rival or exceed their male counterparts in popularity. An important aspect about women's sports is that women usually do not compete on equal terms against men.
Before each ancient Olympic Games there was a separate women's athletic event, the Heraean Games, dedicated to the goddess Hera and held at the same stadium at Olympia. Myth held that the Heraea was founded by Hippodameia the wife of the king who founded the Olympics.
Although married women were excluded from the Olympics even as spectators, Cynisca won an Olympic game as owner of a chariot (champions of chariot races were owners not riders), as did Euryleonis, Belistiche, Zeuxo, Encrateia and Hermione, Timareta, Theodota and Cassia.
After the classical period, there was some participation by women in men's athletic festivals.
During the Song, Yuan, and Ming dynasties, women played in professional Cuju teams.
The first Olympic games in the modern era, which were in 1896 were not open to women, but since then the number of women who have participated in the Olympic games have increased dramatically.
