My top 3: I. Saladin - Treated his enemies with great chivalry and was so generous, when he died and his family opened his treasury to buy him a grave it was empty since he'd given all his money to charity. II. Gandhi - Played a large part in liberating India from British rule. Not what you would traditionally call a "leader" but was so inspiring that many followed him regardless. III. Bismarck - United all the German tribes, was superb at both warfare and domestic politics. Considered by many to be the world's top leader in his time.
