Up until the early 1920s, track and field had been almost exclusively a male-only pursuit. Alice Milliat argued for the inclusion of women at the Olympics, but the International Olympic Committee refused. She founded the International Women's Sports Federation in 1921 and, alongside a growing women's sports movement in Europe and North America, the group initiated of the Women's Olympiad (held annually from 1921 to 1923). Working in conjunction with the English Women's Amateur Athletic Association (WAAA), the Women's World Games was held four times between 1922 and 1934, as well as a Women's International and British Games in London in 1924. These events ultimately led to the introduction of five track and field events for women in the athletics at the 1928 Summer Olympics. In China, women's track and field events were being held in the 1920s, but were subject to criticism and disrespect from audiences. National women's events were established in this period, with 1923 seeing the First British Track & Field championships for women and the Amateur Athletic Union (AAU) sponsoring the First American Track & Field championships for women. Also in 1923, physical education advocate Zhang Ruizhen called for greater equality and participation of women in Chinese track and field. The rise of Kinue Hitomi and her 1928 Olympic medal for Japan signified the growth of women's track and field in East Asia. More women's events were gradually introduced as years progressed (although it was only towards the end of the century that the men's and women's programmes approached parity of events). Marking an increasingly inclusive approach to the sport, major track and field competitions for disabled athletes were first introduced at the 1960 Summer Paralympics.
