Othello is a tragedy because it meets the definition of tragedy in such standard authorities as Aristotle. Aristotle defined tragedy as a story about something that is "serious, complete, and of a certain magnitude" that uses drama to tell of the fall of someone highly placed. This fall occurs because of external or internal forces, especially the chief character's own "error or frailty," his or her "tragic flaw," and the drama ends with the attainment of understanding and a resolution of the fear and pity that it induces.
Othello fully satisfies this definition. Othello himself is a high, admirable character whose downfall arouses pity and fear. He and the other characters in the play are true to life, consistent, and behave logically according to the information they are supposed to have. Their characteristics support the plot -- Othello is jealous (his "tragic flaw") and trusting, Desdemona loving and faithful, Iago evil and devious, plotting the ruin of his supposed master Othello. Othello is brought down due to an external force (the hatred of Iago) working in harmony with his own jealousy, his tragic flaw, to end in his destruction and that of his wife, an equally admirable character. The incidents of the plot arouse pity and fear in the viewers; the situtuation (betrayal by a trusted associate) is universal, and so viewers can envisage themselves tricked in the way Othello is tricked. Finally, the play ends with a katharsis or "purging," a resolution of the pity and fear we feel at seeing Othello tricked into murdering his wife, as Iago is discovered and condemned and Othello fully understands what has been done to him and commits suicide.
Yes, "Othello" is a tragedy. Shakespeare wrote thirty- seven plays; of those 37, twelve of them are labeled as tragedies, most including "Othello" had been written between 1601 and 1608. A Shakespearean tragedy has a few characteristics. First, the main character(s) or protagonists must have a tragic flaw that will bring about his/her final demise yet must also possess characteristics that allow the audience to feel admiration or sympathy for him or her. At the same time, this must be a character that is not completely pure at heart and "goog" but must possess some type of evil in his/her character. The character of Othello in the play possesses these traits. Because of the underlying themes in the play (those of love, jealousy because of love, and murder because of that jealousy), some people would call the play a romantic tragedy, but it is considered a Shakespearean tragedy, nevertheless.
othello is a tragedy because shakespeare created a mood that challenged the way a person see his or her self and the world. subject like racism, sexism, love, hate, jealously, pride and trickery are thoroughly developed in the play
