Women's association football, more commonly known as Women's football or Women's soccer, is the most prominent team sport played by women around the globe. It is played at the professional level in numerous countries throughout the world and 176 national teams participate internationally. The history of women's football has seen major competitions being launched at both the national and international levels. Women's football has faced many struggles throughout its history. Although its first golden age occurred in the United Kingdom in the early 1920s, when one match achieved over 50,000 spectators, The Football Association initiated a ban in 1921 that disallowed women's football games from the grounds used by its member clubs. The ban stayed in effect until July 1971.
