Knowledge of history is essential for newspaper articles.

Newspapers provide us with a wide variety of news. When a news is published, it is mandatory to provide all the information pertaining to that news. To enable better understanding and clarity of the news provided, the study of the similar or parallel event is necessary. Hence, the history of the news needs to be published. Newspapers publish separate columns about the historical information to commemorate a special occasion such as the Independence Day, World Environment Day, etc. The knowledge of history thus becomes essential for newspaper articles.
