Before 1943 there was no such term as genocide. It was coined by a Polish-born lawyer named Raphael Lemkin (1901-1959) and elaborated on in his 1944 book Axis Rule in Occupied Europe. In light of the Nazi atrocities in World War II—especially following the publicity of the Nuremberg Trials—he was able to recommend genocide legislation to be written into international law. In 1948, the United Nations approved the convention for "signature and ratification or accession." It was approved by a 55-0 vote and would become official international law after the twentieth country had ratified it. That happened in 1950, and following the ninety day period stipulated in article XIII, the convention entered into force in early 1951.
As of September 2000, 132 countries have become party to the convention. The most interesting absence is that of Japan. Bolivia, Dominican Republic and Paraguay have all signed the convention but have not ratified it.
