The first part of this final thesis explores the pivotal role of youth and youth-oriented organizations within the broader context of civil society. As primary advocates for the interests and needs of young people, we examine their purpose and objectives, with a focus on their significance in supporting and empowering the youth. These organizations offer various services and support to young individuals, ranging from educational programs and employment opportunities to mentorship and providing a safe space for expression and participation in social processes. Additionally, we delve into the challenges faced by youth organizations, with a specific emphasis on the hurdles encountered in organizing activities, particularly during the COVID-19 crisis. The challenges related to activity organization for youth organizations have been identified based on research involving five youth and youth-oriented organizations, namely: Udruga mladih Lumen – ludbreška udruga mladih entuzijasta from Ludbreg, Nezavisna udruga mladih from Lepoglave, Udruga Amazonas from Zagreba, Mreža udruga Zagor from Zaboka and Mreža mladih Hrvatske as the national youth council and head organization for youth in Croatia. In this context, particular attention is given to the Nezavisna udruga mladih, describing its establishment, evolution, and current status based on the interview with the organization's founder and on the interview with long-time deputy president and active member. Special emphasis is placed on the Jailhouse festival, a youth festival held annually in Lepoglava, now in its twelfth edition. This festival serves as a concrete example of communication activity in practice conducted by the Nezavisna udruga mladih. The continuation of the seminar focuses on a detailed analysis of this festival, encompassing event management, promotion, communication strategies, and social media analysis. Finally, the conclusion presents theses and ideas for enhancing event management derived from the analysis of the festival.
