The article explores the issue of loss of individuali-ty in the war according to theoretical perceptions of existen-tialist philosophers. The problem is observed and discussed, focusing mainly on the cases of two world warsthat emerged in the 20th century. These wars had a huge global impact not only on social and political life worldwide but also on the philosophical perceptions of human life valorization and ex-istence. Based on the comparative analysis of the philosophical views of different thinkers, the article reveals the loss of hu-man individuality both in social conditions and on the onto-logical level.It is concluded that if the philosophy of World War I ob-served death as a unifying factor, including an equalizationthat excludes the individual, then existentialism, as a condi-tion of the reality of widespread death, considers it as a phe-nomenon that opens the spiritual eye of a person to the reality of death. As the development of technology and wars are closely related, world wars represent a direct threat by primi-tive nations that assimilate and use technology to absorb na-tions endowed with a peace-loving and creative spirit. This is a big threat to humanity in terms of its dehumanization and destruction
