Political communication on social media is one of the most influential types of communication aimed at the public. This final paper studies the crisis communication of the Croatian Democratic Union (‘Hrvatska demokratska zajednica’) on social media, with an emphasis on the Facebook page "HDZ – Hrvatska demokratska zajednica". The paper shows how the Croatian Democratic Union, as the largest party in the Republic of Croatia, uses social media, how it responds to a crisis, whether it has established protocols, and how it studies the political rhetoric of posts. The subject of the analysis of this final paper are posts on the aforementioned Facebook page, which are categorized into crisis and everyday communication. The first part of the inductive content analysis looks at posts made in the immediate aftermath of the drone crash in Zagreb in March 2022. The next analysis juxtaposes the communication of the Croatian Democratic Union during the floods in Gunja in 2014 with the communication during the earthquakes in Sisak-Moslavina County in 2020. The reason for this analysis is to compare the communication of the Croatian Democratic Union during a crisis in which the party is part of the opposition versus a crisis in which it is the parliamentary majority. In addition, daily communication and communication with the opposition were analyzed. This turned out to be the biggest challenge in running the Facebook page. Apart from the inductive content analysis, a survey was conducted as part of the paper. It sought to understand the perception of the members of the Youth of the Croatian Democratic Union about the posts on the party page "Mladež HDZ Karlovačke županije” (‘Youth of the Croatian Democratic Union of Karlovac County’). The cases included in the analysis in the final paper occurred in the period from 2014 to 2022 and were singled out as examples of crisis communication that is of exceptional importance to the public.
