This document summarizes several schools of history, including the Marxist School, the School of "Annales", and American schools like the Progressive, Consensus, and New Left schools. It also briefly discusses the historians Plutarch and Hegel. The Marxist School emphasized economic structures and class struggle as drivers of historical change.
