In 2007, of 5,723 faculty in the departments of history at British universities, 1,644 (29 percent) identified themselves with social history and 1,425 (25 percent) identified themselves with political history. From 1975 to 1995 the proportion of professors of history in American universities identifying with social history increased from 31 to 41 percent, while the proportion of political historians decreased from 40 to 30 percent. The research interests of historians change over time, and there has been a shift away from traditional diplomatic, economic, and political history toward newer approaches, especially social and cultural studies. During the 18th-century Age of Enlightenment, historiography in the Western world was shaped and developed by figures such as Voltaire, David Hume, and Edward Gibbon, who among others set the foundations for the modern discipline. During the Middle Ages, medieval historiography included the works of chronicles in medieval Europe, Islamic histories by Muslim historians, and the Korean and Japanese historical writings based on the existing Chinese model. His near contemporaries Sima Tan and Sima Qian in the Han Empire of China established Chinese historiography with the compiling of the Shiji ( Records of the Grand Historian). The Roman statesman Cato the Elder produced the first history in Latin, the Origines, in the 2nd century BC. However, the discipline of historiography was first established in the 5th century BC with the Histories of Herodotus, the founder of historiography. In the ancient world, chronological annals were produced in civilizations such as ancient Egypt and Mesopotamia. The extent to which historians are influenced by their own groups and loyalties-such as to their nation state-remains a debated question. Beginning in the nineteenth century, with the development of academic history, there developed a body of historiographic literature. Scholars discuss historiography by topic-such as the historiography of the United Kingdom, that of WWII, the British Empire, early Islam, and China-and different approaches and genres, such as political history and social history. The historiography of a specific topic covers how historians have studied that topic using particular sources, techniques, and theoretical approaches.

Historiography is the study of the methods of historians in developing history as an academic discipline, and by extension is any body of historical work on a particular subject.
