The 400-plus entries in Atrocities, Massacres, and War Crimes: An Encyclopedia provide accessible and concise information on the difficult subject of abject human violence committed on all continents. The entries in this two-volume work describe atrocities, massacres, and war crimes committed in the 20th century, thereby documenting how human beings have repeatedly proven their capability to commit horrific acts of inhumanity even in relatively recent times and within the modern era. The encyclopedia covers countries, treaties, and terms; profiles individuals who had been formally indicted for war crimes as well as those who have committed mass atrocities and gone unpunished; and addresses human rights violations, crimes against humanity, and crimes against peace.
