Only a few studies have been conducted so far on the long-term impact of war. We investigated whether a life-long impact of the war experiences could be detected in advanced-agers who have successfully overcome all life’s challenges. The participants in this study were oldest-old (80+ years) residents of retirement homes in Zagreb (Croatia), who were divided into two groups – ‘war-exposed’ and ‘not-exposed’ – according to their direct war experience (First World War, Second World War, Croatian Homeland War). Within this 1906–1928 birth cohort, a higher percentage of participants with war experiences reached extreme longevity (95+ years). We found no significant difference (p < 0.01) between the two groups concerning demographic and socio-economic characteristics, their life satisfaction, their self-rated current health and functional ability status. Despite numerous similarities, several traits related to life-history, current quality of life, attitudes and reflections distinguish the group of participants with direct war experience. The kind of war involvement – active military service, imprisonment in concentration camps or prisons, forced migration due to war and war-related death of close family members – stretched through various aspects of the life-history features, quality of life and attitudes. It differed for men and women, so it is no wonder that the significance pattern in the two genders mostly seems mutually exclusive. Socio-economic situations strongly differed by gender and according to the kind of war exposure, amplifying the differences within the ‘war-exposed’ group in terms of the life-long impact of wars on their lives. Therefore, we could claim that the war experiences were not the same for everybody, and that they had lasting consequences on the lifecourse of persons who directly faced war-related events. The results also point to the high resilience capacity as a common feature among persons who survived direct exposure to at least two wars and yet survived to exceptionally old age.
