In literature and film, conflict is a clash between two opposing forces that creates the narrative thread for a story. Conflict occurs when the main character struggles with either an external conflict or an internal conflict. ... Character vs. character. For example, if the protagonist is fighting his or her government, or is accused of a crime he or she didn't commit, these would be examples of Man vs. Society as conflict. If a protagonist is going against the grain of what his or her society and people expect, this is also an example of Man vs. Society conflict. Identify what or who is coming between the protagonist and his goal. If the goal is to get somewhere, and there is a huge storm, then it's a conflict. If the goal is to get a person to fall in love with him, and another person gets in their way, then that's a conflict. The opposing force created, the conflict within the story generally comes in four basic types: Conflict with the self, Conflict with others, Conflict with the environment, and Conflict with the supernatural. Conflict with the self, the internal battle a lead character has within, is often the most powerful. In creative writing, the conflict must be dramatic. Create an opposing force that is just as strong, if not stronger, than your main character. Your protagonist needs to work to overcome obstacles and reach the story goal. A strong antagonist will create a compelling emotional conflict.
