The first part of a four-part series that reveals how a secret pact formed a cartel that controls the world's oil. Throughout the region's modern history, since the discovery of oil, the Seven Sisters have sought to control the balance of power. They have supported monarchies in Iran and Saudi Arabia, opposed the creation of OPEC, profiting from the Iran-Iraq war, leading to the ultimate destruction of Saddam Hussein and Iraq. The Seven Sisters were always present, and almost always came out on top. Since that notorious meeting at Achnacarry Castle on August 28, 1928, they have never ceased to plot, to plan and to scheme.
