"The 'Great man theory' is a theory held by some that aims to explains history by the impact of 'Great men,' i.e.: highly influential individuals, either from personal charisma, genius intellects, or great political impact. For example, a scholarly follower of the Great Man theory would be likely to study the Second World War by focusing on the big personalities of the conflict, i.e.: Winston Churchill, Adolf Hitler, Dwight Eisenhower, etc. This approach to history is associated with the nineteenth-century Scottish historian Thomas Carlyle, who declared, 'The history of the world is but the biography of great men.' Carlyle argued that heroes shape history through the vision of their intellect, the beauty of their art, the prowess of their leadership, and, most important, their divine inspiration. Carlyle’s theories have generally fallen out of fashion."
