Introduction The psychology of a crowd has been at the center of scholars’ attention for a long time, during which multiple theories and implications have been introduced. A crowd as a collectivity of individuals functions according to particular principles, which apply to a crowd as a whole but not to every member individually. In essence, entering the crowd, a person abandons one’s characteristics and obtains new, sometimes foreign features, depending on the characteristics of the collectivity in which they function. Overall, the behavior of individuals is significantly different from the behavior of the same individuals in a crowd. From the historical point of view, the narrative about crowds becomes more relevant when masses begin to play an important role in social and political life. The movements of masses of people, which constitute a crowd, are portrayed in multiple artistic works and might be observed and analyzed. One of the films where the functioning of a crowd is depicted is Martin Scorsese’s 2002 movie under the title Gangs of New York. The film conveys a rivalry between leading gangs dominating New York at the time of the Civil War. Resembling the controversy and multifaceted problematics of the historical time, the director brings the crowds of the gangs to the screen, which presents a fruitful background for the analysis. When classifying the crowd in the gang led by Bill the Butcher, as portrayed in the film Gangs of New York, the classification proposed by Le Bon (1896) might be applied. According to it, the gang led by Bill the Butcher is a heterogeneous organized criminal crowd. The purpose of this essay is to present a detailed analysis of a crowd portrayed in Scorsese’s (2002) film using the concepts introduced in the work of Le Bon (1896). In order to illustrate the applicability of crowd characteristics to gangs’ formation, the concepts and ideas discussed by Le Bon (1896) are used for analysis. Firstly, the psychological attributes of the crowd mind are exemplified and illustrated. Secondly, the opinions and beliefs of the analyzed crowd are discussed based on the concepts of Le Bon (1896). Thirdly, the classification of the crowd is presented in more detail. Finally, the essay concludes with the considerations as per the functioning of the crowd as a distinctive collectivity that is characterized by unique features different from the sum of the features of its constituents. Characteristics of the Crowd in Gangs of New York Psychological Characteristics of the Crowd’s Collective Mind When gathered in a group, people obtain a new set of characteristics, which significantly differ from the ones that might be attributed to people when they act alone. Indeed, according to Le Bon (1896), under particular circumstances, “an agglomeration of men presents new characteristics very different from those of the individuals composing it” (p. 12). The collectivity implies that people move in one direction, according to which they form their patterns of behavior. Such conditions lead to the integration of individuals and the complete vanishing of a conscious personality (Le Bon, 1896). However, these assumptions do not apply to all groups of people who gather randomly. For a crowd to be formed into a psychologi
