On 15 June 1909, at Lord's Cricket Ground in London, representatives of England's Marylebone Cricket Club, Australia's cricket authorities, and South Africa's cricket administration met to formalise the world's first international cricket governance body. The driving force behind the meeting was Sir Abe Bailey, the South African mining magnate and politician whose vision was a triangular Test tournament between the three Test-playing nations. The body created at the meeting was named the Imperial Cricket Conference — 'Imperial' reflecting the British-Empire framing of international cricket at the time.
The three founding members — England, Australia and South Africa — were the only three nations playing Test cricket in 1909, which is why the founding was inevitably restricted to those three. Membership was restricted to governing bodies of the British Empire whose teams played cricket at the highest level. This restrictive framing remained in place until the 1960s and is the reason the body retained the 'Imperial' name long after the British Empire itself had begun to dissolve.
The Imperial Cricket Conference was renamed the International Cricket Conference in 1965, in recognition of the post-imperial framing of the sport and the eventual admission of non-Empire member states. It was renamed again, this time to the International Cricket Council, in 1989 — preserving the ICC initials but updating the body's name to reflect its modern role as a governing council rather than a periodic conference. The 1909 founding is the historical anchor for all three names.
The first triangular Test tournament — the practical reason for the founding — was eventually held in England in 1912. Australia, England and South Africa all played each other in a single tournament, with England winning. The tournament was disrupted by weather and by political differences between the Australian board and several of its players, and the experiment was not repeated immediately. But the governance body that the 1912 triangular had been the proximate reason for had been established in 1909 and would persist long after the tournament itself was forgotten.
