Objectives To delve into the phenomenon of memorial tattoos in Israel following the October 7, 2023, massacre, and the ensuing Iron Swords War utilizing Terror Management Theory. Methodology A qualitative approach employing digital ethnography and visual content analysis was adopted to scrutinize 250 war tattoo images sourced from Israeli tattoo artists’ Instagram pages and Facebook groups. Data collection spanned the initial four months of the war, from October 2023 to January 2024. Findings and conclusions The analysis highlights existential anxieties stemming from the massacre and ongoing conflict, which are both reflected and addressed through the tattoos’ content and meaning. Memorial tattoos serve as responses to mortality salience, depicting themes that adhere to the three anxiety-buffer mechanisms proposed by the theory: reinforcement of collective worldviews; enhancement of self-esteem; and seeking continued attachment relationships. Through these mechanisms, tattoo recipients invest efforts in giving meaning to the inconceivable events and their ongoing grief.
