One of the discussed topics in history lessons in primary and secondary schools are war topics, which are full of violence, suffering, cruelty, wickedness, evilness and carelessness. Therefore, the history lessons have an important and responsible task in how to discuss war topics. The discussion of military operations, diplomatic actions and statistical display of war consequences can be dull and impersonal. The integration of didactic material with scenes of torture and suffering can shock and cause stress or trauma in students, perhaps it may even trigger inappropriate remarks or history aversion. Therefore, various forms of testimonies, personal life stories or case studies are suitable for history lessons about war violence and the suffering of people. Testimonies can be expressed as a record, film display, song, photo story of a preserved photography, short stories, stories or novels with historical background, essays and children drawings, war victims, diaries, etc. The teacher’s responsibility is to choose the kind of testimonies that will cause empathy, compassion and respect for the war victims. Students must note that these testimonies are firsthand sources, and not scientific history, which was written on the basis of different available historical sources. Students should be made aware that they should not be careless observers, but should respond to violence, injustice and violations of human rights.
