British Open

While there had been a professional men's championship for some years, the 'open' men's championship (for both professionals and amateurs) was not inaugurated until 1930.

Charles Read, British professional champion for many years, was designated the first open title holder. Would-be challengers were required to demonstrate they were capable of mounting a competent challenge, as well as guaranteeing a minimum 'purse' (prize money) of £100 (which comprised gate-takings and players' 'subscriptions'). Read subsequently played the first final as the 'defending champion' against challenger Don Butcher in December 1930, but lost in home and away legs. The men's Championship maintained this 'challenge' system format until 1947, replacing it with the current 'knockout' system in 1948.

The women's championships commenced in 1922 as an amateur event, and remained so until 1974. In the inaugural event, Joyce Cave defeated her sister Nancy Cave in the final.

Both Championships have been played continuously since inception, with the exception of the men's championship in 1934 (when no challenger to F. D. Amr Bey entered), and both championships during World War II, and in 2010 and 2011 due to lack of sponsorship. The men's and women's events were originally held separately, but have been held as a joint event since 1983.

The most successful players in the history of the championships are Australian Heather McKay (née Blundell), who won the women's event 16 consecutive times from 1962 to 1977, and Pakistani Jahangir Khan, who won the men's title 10 consecutive times from 1982 to 1991.
