Sabine Bode- Germany
Sabine Bodes bestselling books on the aftermath of war in the age group of German war children and especially in the next generation, called “war grandchildren”, fortifies to ask questions about the Nazi past – a search to reveal family secrets and to work towards individual and societal healing. We talk about a time in Western Germany when research and education concentrated on victims and perpetrators of Nazi regime, a process started in the seventies, leaving behind an era when most Germans assured “We did not know anything” and “We were all victims”, no matter how strongly they had been involved in Hitler Germany. But refusing guilt and shame did not end the case. The feelings changed over to the following generation. This assumed guilt was very common in Germany.

The crucial burden of the war children was not the violence of war but the holocaust. Shame and the feeling of being guilty blocked the access to their own trauma and mental disorders. What we have to consider: Germany especially West Germany was extremely busy in the process of coming to terms with the past for 30 years. But it was done academically – mainly the work of historians and publicists. In most families a voiceless past still reigned. Guilt and shame hindered even the perception of feelings and the dealing with own traumatic experiences. It appears like a late awakening. Due to the silence about family past and the lack of emotions how memories were passed over to the next generation the children of war children had been far away from measuring their parent’s childhood drama. But 70 years after the end of the World War II quite a number of media presentation focussed the group of “war grandchildren” and pushed the issue of the aftermath of war in contemporary family relationships. Depotismen, oppression and war do not stop when the weapons are laid aside.

The legacy of violence are to a large extend non-functional family-relationships. But this is not the end of it. Social and cultural factors – and very much so knowing the truth of the past – can help to reduce stress symptoms, overcome a health crisis and may lead to a healing of intergenerational conflicts.
