It is known that it is necessary to enrich the tourist offer of each tourist destination in order to create long-term success, and how much cultural tourism, or its subtype, event tourism can contribute to the development of tourism in a particular area or attract new tourists is unknown. Special emphasis can be placed on this form of tourism, since during 2020 and the impact of measures to combat COVID-19, event tourism is actually one of the types of tourism that can be most affected by the prescribed measures, since these are events with mass gatherings . On the other hand, events organized outside the summer season have the potential to develop year-round tourism in a particular area. The aim of this paper is to analyze the possibilities for the development of event tourism in the Republic of Croatia on the basis of existing events that are held regularly, but very often are not sufficiently known to the citizens of the Republic of Croatia, much less tourists. In the theoretical part of this paper, tourism is conceptually defined and the history of tourism development at the global level and in the Republic of Croatia is presented, special emphasis is placed on the importance of tourism for the Croatian economy, which is why certain statistics are presented. Conceptually, event tourism is defined as one of the subtypes of cultural tourism, which is analyzed in detail in this paper. The empirical part of the paper presents examples of some of the events that are very important for the development of event tourism in the Republic of Croatia, and also highlights the potential for the development of event tourism in the Republic of Croatia based on the presented events. It is possible to conclude that there are many events in Croatia, but which are not sufficiently covered by the media (which is why they are poorly known in Croatia, and even less tourists), which is actually one of the necessary prerequisites for further growth of these events and attracting more tourist.
