In this thesis, I would like to argue that certain traumatic events have the force to change the victims’ and their families’ lives and with the help of this shared experience, they are able to create significant collective, or even historical memories, that society will probably embed in their cultural heritage. By contrasting and analysing Pat Barker’s Regeneration trilogy’s first and last piece, I have the goal to put the emphasis on the phenomenon of ‘gender’ as well, and grab the opportunity to demonstrate that it is one of the main features that determines social norms and cultural heritage of manhood.I would like to demonstrate how traumatic experiences or memories work, and what impact they have on the victim. I also set the goal to highlight how different cultures deal with traumatic notions such as death. I also wanted to accentuate the "positive" side of the war, because it accelerated to development of the psychology and therefore the need to accept mental problems. All in all, I tried to highlight that not too many differences can be found between Par Barker's two pieces of the Regeneration trilogy.
