Several crimes recognized in international criminal law are intimately linked to the horrors of the holocaust. Persecution, extermination, and genocide are historically intertwined notions that in all minds refer to the ordeal of the Jewish people before and during the Second World War. This is particularly so with genocide. The 1948 Convention on the Prevention and Punishment of the Crime of Genocide (the ‘Genocide Convention’) is a legal answer to the holocaust. Yet, as any legal notion, genocide goes beyond the characterisation of a specific historical tragedy. It is fated to evolve through legal interpretation, which operates pursuant to certain rules and principles that only subsidiarily rely on the drafting history.
