Many plays, television shows and movies that are made from real life events include dramatic events into the story so that the audience will be more entertained. They base the storyline on the events of the true story, but add fictional characters and events into the plot to make it more fun to watch. The same can be said for William Shakespeare’s Julius Caesar.
Julius Caesar was a real person who did die from a large group of conspirators that helped stab Caesar to death. However, Shakespeare added in fictional accounts to make the play better. So, the Julius Caesar play is both fictional and a real story depending on which element you are talking about. Most likely the main characters are the same.
It is both historical and fictional. Historical sources focus on the facts of the assassination, while fictional works focus more on the characters and the drama of the story. Shakespeare strives to make the details and the dramatic elements of the story interesting and enjoyable. When looking at the tale fictionally, you get to see what happened. When looking at it historically, you get to know why it happened.
Also, in the historical account, the conspirators had planned for much longer than in the fictional account. Even though Shakespeare is faithful to his sources in the general outlines of the plot, he is not writing about history. Also, Shakespeare's dramatization of the language used by the characters is fictional.
