The first-ever women's singles Wimbledon Championship was won by Maud Watson of the United Kingdom in 1884. Watson defeated her sister Lillian Watson in the final, winning 6-8, 6-3, 6-3. The tournament was only open to women's singles players that year, and it attracted a field of 13 players. The first men's singles Wimbledon Championship had been held the previous year in 1883. Since then, Wimbledon has become one of the most prestigious and highly regarded tennis tournaments in the world, and it is widely considered to be one of the four Grand Slam tournaments.
