It was "the first time, anywhere in the world," that a former head of state was being tried for genocide by a national tribunal, according to the United Nations. <a href="http://www.cnn.com/2013/05/21/world/americas/guatemala-genocide-trial/index.html" target="_blank">The conviction was overturned</a> 10 days later, however, and Guatemala's Constitutional Court ordered a retrial.
