The book “Azerbaijan and the armeninan issue in Caucasus”, by Rizvan Gusseinov proved on the basis of many poorly studied or completely unknown archival materials, medieval manuscripts and sources the mendacity of the major postulates of an armenian propaganda about history, culture and habitat of historical Azerbaijan. It also shows the hidden mechanisms of centuries-old techniques of appropriation of the culture, history, spiritual and architectural heritage of other nations, used by armenian propaganda, their ideological and historical sciences.
