The Grand Nagus was the leader of the Ferengi Alliance. He was both the political leader of the species as well as the economic leader. Virtually all decisions that affected the Ferengi required the approval of the Grand Nagus, whose power was supported by the Ferengi Bill of Opportunities and backed by the Board of Liquidators. (DS9: "Profit and Lace") The Grand Nagus possessed the ability to appoint a Grand Proxy to act in his name in matters which he was unable or unwilling to deal with personally. (VOY: "False Profits")
