Answer 1

1. The answer appears to be 1888 (1889 in (c) below seems to be incorrect).

(a) "But back to history. First two big mines formed, the De Beers and Kimberley mines. Cecil John Rhodes and Charles Rudd gained control of both mines and merged them, forming De Beers Consolidated Mines Limited in 1888."

(b) "On the 13th of March 1888 Rhodes and Barnato united their interests in the De Beers Consolidated Mines Ltd. except for 25, all shares were now in the hands of four people: Barnato and F.S. Philpson (of the Kimberley Central Diamond Company) and Rhodes and Alfred Beit of the De Beers Mining Company."

(c) "By 1889, the future of the diamond world depended on the outcome of a battle for total control between Rhodes' De Beers and Barnato's Kimberley Mines, each backed by powerful overseas interests. Rhodes emerged the victor, a cheque for £5,338,650 changed hands and the two mines were brought under the control of a new company, De Beers Consolidated Mines"
