Wimbledon was first competed in 1877. The women's single and the mens doubles events began seven years later in 1884. It has always been played during the summer. It is played over two weeks, from late June to the beginning of July. The tournament is played after the French Open and before the U.S. Open. In 1968, the championships were opened up to both professionals and amateurs for the first time, with Rod Laver and Billie Jean King winning their respective singles titles.
