In this paper, I analyze the Western genre and what makes it such a timeless form of expression. Although the Western genre appeared even before the advent of film technology, the main focus of my analysis is providing an insight into its cinematic nature. Therefore, in my paper, I focus on the key components of this genre, one mostly conveyed through film, and I try to unravel the core of the theme of a Western as a film genre – its myth. The monographs History of Film (2009) by Ante Peterlić and What is a Film? by André Bazin were the most useful titles in my analysis of the subject as they were the most precise in their depiction of the development of Westerns. At the beginning of the paper, I define a film genre, which serves as the basis for my analysis of the Western genre, after which I continue with a description of the history of Westerns in the context of the American colonization of the West while providing more insight into the concept of a myth and what constitutes the protagonist of a Western. I also divide Western genre into their subgenres and give examples of Western films that marked the genre throughout its history.
