Currie was the founder of the Castle Shipping Line, which transported English touring sides to South Africa and back. He had funded Major Warton's 1888-89 tour out of his own pocket, partly because he saw cricket as a useful cultural bond between Britain and the Cape. As the tour ended he donated a trophy to be played for between South African colonies.
The first competition was a one-match affair in March 1890: Kimberley v Transvaal at Newlands, with Kimberley winning. This was effectively the first first-class cricket match played in South Africa.
From 1892-93 the format became a proper league between four (and later five) colonial sides — Western Province (Cape Town), Eastern Province (Port Elizabeth), Natal (Durban), Transvaal (Johannesburg) and later Griqualand West (Kimberley). The Currie Cup ran continuously through to South Africa's isolation in the 1970s, was renamed several times after the readmission, and exists today as the CSA 4-Day Domestic Series with the original Currie Cup trophy still presented to the winners of the top division.
Currie himself was knighted in 1881 (he was already KCMG). He was a Liberal MP, philanthropist, and the man whose ships brought half the early Australian touring sides home to England. He died in 1909.
