Primary source is a piece of information created at the time of an event. It provides direct evidence from the past. Primary sources are important in historical study.

Letters written during a war, photographs from an event, or tools used by past societies are examples. These items are often kept in museums, archives, or historical sites. They show what people experienced or recorded at that time.

Historians use primary sources to study events closely. These sources can include objects, written records, or audio and visual materials.
