Unlike widely reported genocides - such as those in Nazi Germany, Rwanda, and Cambodia - some atrocities remain unacknowledged, denied, and excluded from history textbooks. Yet, the buried past is important. Not only because perpetrators of gross human rights violations should be held accountable, but also because victims and their descendants warrant recognition. Hushed Voices analyzes 15 key cases of forgotten mass political violence from around the world. These include: a) in Africa: Zanzibar, Zimbabwe's Gukurahundi, Biafra, the Algerian Harkis, and the Mau Mau anti-colonial rebellion; b) in the Middle East: Armenia, the Palestinian Nakba, and Hama in Syria; c) in Asia: Suharto's slaughter of half a million Indonesians, Imperial Japan, and Gujarati Hindu nationalism; d) in Europe: the Ukrainian Holdomor, the Spanish Civil War, Dresden, and the ethnic cleansing of Germans in Poland and Czechoslovakia after World War II.
