History is the systematic study of past events through organized knowledge. The purpose is not just to list events but to find patterns and meaning. Historians study surviving records to write histories and interpret the past. Studying history helps understand the present, develop a sense of identity, and provides context for other disciplines. It also teaches critical thinking skills. Historians rely on primary sources like documents and artifacts as well as secondary sources like histories to research and interpret the past. The historiography of Ethiopia and the Horn has developed over time from early accounts to modern historical studies using a variety of written and oral sources.
