Economic history is the study of economies or economic phenomena of the past. Analysis in economic history is undertaken using a combination of historical methods, statistical methods and the application of economic theory to historical situations and institutions. The topic includes and business history and overlaps with areas of social history such as demographic and labor history. The quantitative – in this case, econometric – study of economic history is also known as cliometrics.
In Germany in the late 19th century, scholars in a number of universities, led by Gustav von Schmoller, developed the historical school of economic history. It ignored quantitative and mathematical approaches. Historical approach dominated German and French scholarship for most of the 20th century. The approach was spread to Great Britain by William Ashley, 1860-1927, and dominated British economic history for much of the 20th century. In France, economic history was heavily influenced by the Annales School from the early 20th century to the present. It exerts a worldwide influence through its Journal Annales.

Treating economic history as a discrete academic discipline has been a contentious issue for many years. Academics at the London School of Economics and the University of Cambridge had numerous disputes over the separation of economics and economic history in the interwar era. Cambridge economists believed that pure economics involved a component of economic history and that the two were inseparably entangled. Those at the LSE believed that economic history warranted its own courses, research agenda and academic chair separated from mainstream economics.
