In order to thoroughly analyze the marketing strategy of the MoSt association. In the first part of this final thesis, the essential terms that we associate with non-profit organizations and the marketing of non-profit organizations are defined. The main goal of this final paper was to analyze the marketing strategies of the MoSt association and to show its success achieved by the association over the years. For the sake of easier understanding and presentation of the marketing of the entire organization, a project named "Udarac" has been singled out. In this project, the problem of violence among young people and the problem of juvenile delinquency was highlighted, and the goal was to raise awareness of the problem in order to encourage professionals to find a solution, and to make society aware of its existence. Various forms of visual communication, plays, exhibitions showed the consequences caused by the criminal acts of minors. In addition to the "Udarac" project, the MoSt association carried out various humanitarian actions, such as actions to help raise funds for the homeless. From this example, we can see the importance of applying marketing in the MoSt association, but also in all non-profit organizations. In the "Blow" project, all marketing strategies were aimed at making the public "aware" of the existing problem and calling for help. After the implemented project, the society noticed the very importance of the existence of not only the MoSt association, but also of every non-profit organization whose goal is the welfare of society.
