On February 24, 2022 Russia launched a full-scale invasion of Ukraine, an event that significantlyaltered the European security landscape and intensified scholarly interest in information warfareand strategic narratives. In a series of speeches Vladimir Putin has sought to justify and legitimizeRussia's military actions through the use of strategic narratives. The study is conducted using aqualitative narrativeanalysis methodology that aims to describe how Russian strategic narrativesused to legitimize the invasion of Ukraine 2022 and how these narratives change between the year2022 and 2024. The theoretical framework used is based on Miskimmon et al. strategic narrativetheory and focuses on three central key categories: systemnarrative, identitynarrative andpolicynarrative. The results of the study show that strategic narratives are dynamic and adapt tothe different phases of the conflict. Initially the narratives are used to establish a threat image andlegitimize the invasion as necessary, while in later stages during the conflict the narratives arereshaped to maintain the legitimacy. The study contributes to an increased understanding of howstrategic narratives are used as a tool in modern conflicts where information warfare is a centralpart of legitimizing military actions.
