Military Leaders are the leaders of the military forces—armed forces, armed services, military, military machine, war machine—of a nation. Military leaders influence others by providing purpose, direction, and motivation to accomplish the mission, and have the legal authority to lawfully exercise control over subordinates by virtue of their rank or position. Warlords who exercise absolute civil power and individual autonomy in regions where the government is weak are also considered to be military leaders. History is replete with the legends of military leaders and revolutionaries who left their indelible marks on human civilization. Alexander the Great, who established one of the largest empires of the ancient world, is undoubtedly one of the best known military leaders. Ancient China’s Sun Tzu was not just a brilliant military leader, but also the author of ‘The Art of War’, an ancient Chinese text on military strategy. While Saladin, William the Conqueror and Henry V were the famous military leaders who lived during the Middle Ages, Oliver Cromwell, Shivaji and Peter the Great were courageous warriors of the Early Modern Period. Even though a majority of military leaders throughout history have been men, brave ladies like Joan of Arc, Boudicca, Laskarina Bouboulina, and Lakshmibai have proven that women too can be powerful military leaders. Read on to discover about the life and works of various famous military leaders from all over the world.
