Historical research involves systematically collecting and evaluating past data to understand and explain past events and actions. It aims to reconstruct what happened in the past as accurately as possible without manipulating variables. There are different types of historical research focused on topics like institutions, influences, or ideas. The process involves identifying a topic, collecting and evaluating primary and secondary sources, interpreting data, and synthesizing conclusions. Historical research is important as it can provide context, uncover unknown events, study causes and effects, and help understand present situations by examining relationships between past and present.
