Simmel is one of the most important thinkers in the discipline of sociology and his work in the micro field is particularly important. While Simmel focuses on urban life, he also focuses on how people relate in urban life. He has ideas about how people's behavior changes when they are one person, two people, three people. These ideas are confirmed by different thinkers today.

In addition, the concept of conflict, which is the subject of this study, is one of the subjects that Simmel worked on. Simmel looks at conflict through culture, or more precisely, through objective culture and subjective culture. This coincides with the object-subject distinction, one of the basic dichotomies of sociology.

The reason for choosing this topic is the different reflections of the concept of "conflict" in daily life, cinema and theater. While Simmel argues that conflict causes the tragedy of culture and erodes the individual mind, in communication sciences it is possible to speak of both positive and negative effects.

While the destructive side of conflict often comes to the fore in daily life and communication, conflict in theater serves to reinforce a dramatic structure. Cinema, on the other hand, activates people's emotions through conflict, sometimes opening up human perception and sometimes deconstructing it.

Life without conflict can have a pleasant effect on people - even if it seems boring - but theater and cinema without conflict - regardless of the style and the product of the period - are unthinkable.

One of the most important conflicting characters in the history of cinema is the Joker, with his internal conflict in his own world and his structure that challenges the world and wages war. Although he is considered an anti-hero, he is a character that the audience can easily identify with and he has been portrayed by various actors around the world, all of whom have made an impact. This is undoubtedly due to the fact that he is a character that feeds on conflict and is an anti-hero. In addition, post-modern art and cinema focus more on the losers, the oppressed, the little people. The study will follow a path from what thinkers such as Simmel, Lefebvre and Horkheimer say to theater and cinema.
