Media and society are phenomena that, in combination with political, cultural and economic elements, form a dynamic research field. At local and global levels, individual and society network and create global communication power. Interaction through the media modifies and transforms social relations resulting in changes in the social structure. Social networks have brought a new form of communication, which is reflected in informing citizens and increased social awareness of events in the world. Due to the dynamism of the transmission of the political and war situation in Ukraine, the Russian-Ukrainian conflict was called the first “TikTok war”. The main goal of this thesis is to show the role of the social network TikTok during the state of war in Ukraine in 2022 and 2023. Qualitative analysis was used of a total of 100 posts, 25 posts with the most reactions tagged with one of the four frequently used hashtags related to the Russian-Ukrainian conflict (#ukraine, #ukrainewar, #prayforukraine and #warinukraine). The posts are classified into thematic categories titled Views from the battlefield, Support, Viewing and commenting of politicians and Ukrainian TikTokers, and category named Other, which contains posts whose subject matter is found less often than the previously mentioned categories. Content analysis shows the manner of reporting in the context of war and the state of war and its far-reaching consequences. The specificity of these announcements is their seriousness and informativeness, which goes beyond the classic task of TikTok which is "encouraging creativity and bringing joy".
