This document discusses the definition and nature of history as an academic discipline. It covers key topics such as the types of sources used in historical research, including primary and secondary sources. Primary sources are original materials like documents, artifacts, and eyewitness accounts created during the time period being studied. Secondary sources are produced later by authors who have analyzed and interpreted primary sources. The document also examines different approaches to studying history, like positivism which relies on empirical evidence, and post-colonialism which critiques colonial influences on histories of formerly colonized nations.
