On August 28, 1928, in the Scottish highlands, began the secret story of oil.
Three men had an appointment at Achnacarry Castle - a Dutchman, an American and an Englishman.
Henry Deterding (Dutch Royal Shell) Walter C. Teagle (Standard Oil) John Cadman (Anglo-Persian oil Company, soon to become BP
That August night, the three men decided to stop fighting and to start sharing out the world's oil. Their vision was that production zones, transport costs, sales prices - everything would be agreed and shared. And so began a great cartel, whose purpose was to dominate the world, by controlling its oil.
Four others soon joined them, and they came to be known as the Seven Sisters - Exxon, Shell, BP, Mobil, Texaco, Gulf and Chevron - the biggest oil companies in the world.
