This book is a product of 18 years of research and writings on the issue of the Balkan and especially the Yugoslav national identities, nationalism, state formation process, inter-ethnic and inter-confessional clashes, atrocities, war crimes, ethnic cleansing and genocide committed in this part of Europe and above all on the territory of the ex-Yugoslavia(s) in historical perspective. The reaseach on the topic was begun in 1995 at the Central European University, Budapest Colleage in Budapest, Hungary when I was M.A. student. From that time up today the reaseach was done in several countries where I was using the libraries and archives. As a product of this extensive research several articles was written and published in scientific journals together with a dozen of columnist articles published in several juournals and many internet pages. I hope and believe that the research results presented in this book are going to be of certain value for the sake of better undertanding of the process of the bloody destruction of the ex-Yugoslavia in the years of 1991−1999 in order to prevent the next wars and atrocities between and among the Yugoslavs.
