This study examines digital media activism during the full-scale war in Ukraine caused by the Russian invasion in 2022, focusing specifically on Instagram content posted by users with connections to Kharkiv city between March 18-25, 2022. Kharkiv was heavily affected by bombings throughout the war.  The theoretical framework combines Bennett and Segerberg’s (2009) theory of connective action with Vegh’s theory of internet activism (2013) and Earl et al.’s (2010) perspective on Vegh’s theory. Additionally, the analysis, observations, and theory review led to the development of an additional category, building upon Bennett and Segerberg’s (2009) theory of connective action.  The research methodology involves a four-step toolkit comprising qualitative content analysis, semiotics (denotation and connotation), and anchorage. The analysis of patterns and classification confirms the high level of involvement in digital media activism by users and reveals differentiation based on the purpose of communication. Semiotic analysis and anchorage demonstrate the intellectual and emotional engagement of Ukrainians in digital society and their efforts to provide information and support.  The study introduces a new classification of digital media activism for content analysis and establishes a new category within the theoretical framework. It expands possibilities for future research on digital media activism and online activity during war or similar life-threatening situations. Furthermore, the study presents a methodological toolkit applicable to limited content formats such as Instagram stories, Facebook Stories, and Snapchat.
