Historical methods
The historical method comprises the techniques and guidelines by which historians use primary sources and other evidence to research and then to write history.
Herodotus of Halicarnassus (484 BC – ca.425 BC) has generally been acclaimed as the "father of history". However, his contemporary Thucydides (ca. 460 BC – ca. 400 BC) is credited with having first approached history with a well-developed historical method in his work the History of the Peloponnesian War. Thucydides, unlike Herodotus, regarded history as being the product of the choices and actions of human beings, and looked at cause and effect, rather than as the result of divine intervention. In his historical method, Thucydides emphasized chronology, a neutral point of view, and that the human world was the result of the actions of human beings. Greek historians also viewed history as cyclical, with events regularly recurring.
There were historical traditions and sophisticated use of historical method in ancient and medieval China. The groundwork for professional historiography in East Asia was established by the Han Dynasty court historian known as Sima Qian (145–90 BC), author of the Shiji (Records of the Grand Historian). For the quality of his timeless written work, Sima Qian is posthumously known as the Father of Chinese Historiography. Chinese historians of subsequent dynastic periods in China used his Shiji as the official format for historical texts, as well as for biographical literature.
