The thesis titled "The Specifics of Public Relations in Sports on the Example of the Croatian Judo Federation" analyzes how public relations are shaped and adapted to target audiences through various communication channels, with a special focus on the Croatian Judo Federation. It also addresses segments of corporate social responsibility and highlights the importance of these aspects for quality and long-term public relations. This thesis presents specific and diverse projects organized by the Croatian Judo Federation and analyzes the communication of these projects and their presentation to target audiences on social media. The Croatian Judo Federation was chosen as the subject of this research because it implements projects that serve as examples of best practices, from which some general conclusions about the communication of sports projects, which are an inevitable part of public relations in sports, could be drawn. The research is based on the analysis of online communication through the official profiles of the Croatian Judo Federation, focusing on projects aimed at strengthening relationships with various publics. For this purpose, the thesis first presents specific projects, followed by a content analysis of social media in the research section, providing an overview of the use of Instagram, Facebook, and YouTube as communication channels with target audiences. The final part of the thesis concludes that public relations are crucial for the long-term success of sports organizations. A successful PR strategy enables sports organizations like the Croatian Judo Federation not only to promote sports results but also to build a recognizable identity through other projects both nationally and internationally, while also making a significant contribution to society as a whole.
