In drama, unity refers to the three principles derived from Aristotle's poetics which necessitate a play to have a single action which is represented as happening in a sole place and within the course of a particular period. There principles are called unity of action, unity of place and unity of time respectively. In unity of action, a play is supposed to have a single main action that it follows and have a few subplots or none at all while in unity of place, a play must cover a sole physical space and must not try to compress geography or the arena represent more than one place. In regard to unity of time, the action within the play must take place for 24 hours or less. Aristotle's concept also suggests that in a piece of art, all the elements must be arranged in a manner that they will work according to the overall design of the art and also conveying the main purpose. Therefore, according to Aristotle, the action of a play should be restricted to a single plot, that is, unity of action, should be acted in a single location, that is, unity of place, and the play should have all its events taking place in a single day, that is, unity of time.
